5:55 PM 12/6/96 ================= INTERNET TUTORIAL ================= This document contains important information not available in the printed documentation or in the online Help. The information below describes some solutions to problems that you might encounter while using the program. There are also frequently asked questions and answers listed below. ============ INSTALLATION ============ The Setup program prepares your computer to run this Internet Tutorial CD-ROM. To run the Setup program: · In Windows 95, select Run from the Start menu in other versions of Windows, select File, then Run. · In the command line, type D:\SETUP.EXE (where D: corresponds to your CD-ROM drive). · Click OK. · The Setup program creates the C:\XNETUT32 directory (or one you specify) for you. · For Windows 95, it also copies some DLLs to the \Windows\System sub-directory. · For earlier Windows versions, it also copies one or more DLLs and other system files from the \dlls directory on the CD into the \windows or \windows\system directories on your hard drive. NOTE: Newer versions of these files will not be overwritten. In addition, the Setup program prompts you if you need to install the latest version of Video for Windows (VFW). After installing VFWs, you must restart your computer. You may re-install VFW at any time by running SETUP.EXE in the VFW11 directory on this CD. You DO NOT need VFW with Windows 95. The Setup program makes sure that Internet Tutorial is looking in the right place for the CD drive. If, for example, the drive letter has changed as a result of a system change (i.e.,if a disk or other device has been added or removed), then Internet Tutorial will fail to find its CD-ROM. You can check that the drive letter is correct by using Windows File Manager (or Explorer for Windows 95) to see which letter is assigned to the CD drive. Running the Setup program again will solve this problem. ============================= VIDEO PLAYBACK CONSIDERATIONS ============================= For best results on older or slower machines, play the video in 8-bit (256) color mode. Video playback is slower in any video mode other than 256 colors. Check Windows Setup to ensure that you are using a 256 color video driver. The Windows Setup is usually in the Main group of the Windows Program Manager for Windows 3.1, or under the Display icon from the Control Panel for Windows 95) You can also improve video playback, and overall program performance, by increasing the amount of buffer memory that your CD-ROM driver software uses. Most computers communicate with the CD-ROM drive through the Microsoft MSCDEX driver (for Windows 3.1). You can sometimes improve performance by adding /M:64 to the MSCDEX entry in your AUTOEXEC.BAT file. This increases the number of sector buffers from the default of 4 to 64. ========================== SHARE IN AUTOEXEC.BAT FILE ========================== Unless you are running Windows for Workgroups (3.11) or later versions of Windows, your AUTOEXEC.BAT file should include the line: "SHARE /L:500 /F:5100" or something similar. The /L parameter sets the number of locks, and the /F parameter sets the number of bytes of file space used to record file-sharing information. The values shown above are the minimum values required by OLE applications. Recent versions of Windows do not require this line. =============== TROUBLESHOOTING =============== ===== VIDEO ===== Q: Videos do not play (in earlier versions of Windows before Windows 95): A: You may not have the correct driver. Change the driver to one that works. Internet Tutorial works best in 800 X 600 mode. ===================================================================== WARNING : SELECTING THE WRONG DRIVER COULD STOP "WINDOWS" FROM WORKING. MAKE SURE YOU SELECT A DRIVER THAT IS AVAILABLE ON YOUR SYSTEM. GET HELP IF YOU HAVE NEVER CHANGED DRIVERS BEFORE. ===================================================================== If video still does not play, make sure you are using the latest video driver for your video board. Contact your video board manufacturer for more information. You may also be able to obtain updated drivers from CompuServe in either the Microsoft forum or in a forum managed by your video board manufacturer. Q: Videos do not play under Windows 95: A: You may not have the correct driver. Internet Tutorial works best in 800 X 600 mode. Windows 95 makes it easy for you to change into this mode: click on Display from the Control Panel, then Settings. Q: Video looks choppy. A: Video looks choppy because your CD-ROM drive cannot play the video fast enough. If your CD-ROM drive does not generate a fresh picture every fifteen seconds, you can see the delay between pictures. To speed up video playback: Q: Soundtracks in the videos are choppy (the people are stuttering). A: The soundtracks are not keeping up with the videos. To permanently fix this problem: · Choose the Drivers icon from the Windows Control Panel. · Double-click the line reading, "[MCI] Microsoft Video for Windows." · Click the checkbox next to the "Skip video frames if behind" option so that an "X" displays in it. · Click the Set Default button. If you use older versions of Windows Sound System and other drivers, the audio may be out of synch with the video. Obtain updated Windows Sound System drivers from the Windows Driver Library (WDL). For more information about the WDL, contact Microsoft Product Support. For third-party drivers, contact your sound board manufacturer's technical support department to obtain an updated driver. ===== AUDIO ===== Q: Audio volume is either too high or too low, and you cannot adjust it on your speakers. A: Adjust the volume on your sound card. To adjust the volume on your sound card when running Windows 95, click the "sound" icon on the taskbar. To adjust the volume on your sound card for earlier versions of Windows: · Find the icon for your sound card program group in the Windows Program Manager. It is usually called "sound" or something similar. · Find the icon for the Mixer program and run it. · Adjust the volume and/or mix of sounds. Some sound cards have software that allows you to adjust the volume AND tone of the sound; start with these tone controls set in the mid position and your volume level set between 80 - 100%. This should give a clear signal with no distortion. If treble or bass is added in this software, you must reduce the volume to compensate, or distortion will occur. Check your sound card manual for the optimum settings. Q: Audio does not play. A: Make sure that the volume for your speakers is set to an audible level. If your system has a mute option, make sure it is not in effect. If audio still does not play, check that your sound board is set up correctly. Check to see that the audio driver that came with your sound board is installed correctly and, if necessary, reinstall it. See the documentation that came with your sound board for more details. ====== MEMORY ====== Q: You receive an Out-of-Memory error. A: Close all unnecessary applications. You may find more memory becomes available if you restart Windows. If you are running Windows 3.x in Enhanced mode (the default mode if you are running Windows 3.x on a 386 or better machine), create a permanent swap file on your hard disk. A swap file uses some hard drive space as memory. NOTE: If you have not defragmented your hard drive in a while, be sure to do so BEFORE creating a swap file. Otherwise, Windows may not be able to find a large enough area of disk space to use as memory. Use the DOS DEFRAG command, or another utility to defragment your hard drive. To create a swap file: · Double-click the 386 Enhanced icon in your Windows Control Panel. · Click the Virtual Memory button on the right. · If you don't see the word "Permanent" in that box, click the · Change>> button and select Permanent in the Type field. Q: Internet Tutorial, like other Windows applications, stores temporary files in the \TEMP directory on the hard drive. Ordinarily, Internet Tutorial will clear this directory automatically. In case of a program or system failure, you may have to delete temporary files manually. A: To check the \TEMP setting and/or delete temporary files: · Exit from Windows. · At the MS-DOS prompt, type SET and press . This gives you a listing of the MS-DOS environment settings. · Confirm that one of the settings is TEMP= followed by a valid path. · When you find the TEMP= setting, check the amount of disk space available on the drive where your temporary directory resides. · If you do not have enough disk space, delete unnecessary files from the drive, or move the \TEMP directory to a partition that has enough disk space and change the SET TEMP= line in the AUTOEXEC.BAT file. Usually, it should read something like "SET TEMP=C:\TEMP". · Reboot your machine after modifying the AUTOEXEC.BAT file. ======= DISPLAY ======= Q: Versions of ATI's video accelerator prior to 2.1 do not work well with Video for Windows version 1.1. Installing the accelerator software after installing Video for Windows can overwrite Video for 1.2. Windows version 1.1 components with components from the previous version. A: Avoid installing any version of the video accelerator unless it is specifically noted to be compatible with Video for Windows version 1.1. To obtain an updated version, you can contact ATI's customer support at (905)882-2626. Q: Your customization data has been lost or corrupted. This data is stored in a file called utitle.ttl in your C:\XNETUT32 directory (or the directory you created during setup). A: The latest version of the INTERNET TUTORIAL program always saves a backup copy of your customization data in a file called utitle.bak in same directory as the utitle.ttl file. Copy this file to utitle.ttl.
