In practice, I have found that you can only squeeze the video data "so much" before the quality degrades too much. Generally the "blocks" appear during "cloudy" or "fades" type scenes. I am working on finding a solution for - what we are doing, HQ BACK-UPS - of our movies. Bear with me, RL sometimes needs attention...

P.S. I did finish the 3-movie menu, but a hard-drive upgrade "crash" prevents me from sharing it right now. I do have a friend for whom it was made that has a copy, and as soon as I can get it, I'll post it.
