Divide a 4:3, 720x480 frame into 8x8 blocks. That's the size of the macro blocks on your letterboxed version. Divide the picture only (mostly), 720x480 frame into 8x8 blocks. That's the macro block size of your anamorphic version."
Okay, I get what you are saying. Unfortunately, there is stll a problem. If one wants the anamorphic version, buy plays it on a 4x3 television, then even more resolution is being lost because the player is throwing away visual information to make it fit the screen. There's no point in throwing out buckets of visual information to "cover up" a few glitches (which, again, is why I am using Combustion 3, and also why I intend to master both versions.)
BTW, thank GOD for VirtualDubMod. I was going to give you a screenshot of my MPEG, because the whites in my Tantive flyover were being crushed in the MPEG, and I couldn't figure out why. However, in VDM, the whites were fine. After looking at my DVDMax settings, I changed it from "theater" mode to "original" mode, and the whites are fine now. I've been trying to fix this fucking problem for weeks! Argh!
