Gosh wouldn't we all wish that was true. This is my logic on this. If lets say you 
render something at 320x240 wanted to transfer it to video. PAL resolution here is 
768x576. The 320x240 image has to be interpolated to 768x576 PAL to be transfered to 
video. We all know that when we interpolate an image it appears blocky and aliasing 
will be more obvious. Even though VHS will only record 240 lines the quality coming 
from a 768x576 render would be significantly higher than 320x240. Well thats my logic. 
anyone care to comment?
