I'm assuming you want a comparison between SD Avia and DVE. HD DVE is available, but I can't make a comparison to it because I don't own it.
1) These disks are HD formats, and won't play in a regular DVD player like Avia or DVE.
2) There are no tutorials on AVS HD, where Avia and DVE contain a wealth of information about TV's in general, as well as how to use the test patterns.
3) AVS HD is geared toward the more experienced user, as it contains only test patterns and you must know how to use them with no explanation on the disc. There is a basic patterns section that is pretty easy to use without instrumentation, you just need to do some reading in the first post of this thread.
4) AVS HD is encoded with Rec. 709 matrix, as the name suggests, which is suitable for HD.
5) There are some patterns on AVS HD that aren't on Avia/DVE, and vice versa. Most notably, AVS HD has no calibration tests for audio.
That is about all I can think of. Of course, AVS HD is free, so it doesn't hurt to download it and try it out
