I agree with Erica about the DVD compression. When I look closely at some very fast moving subjects on DVD's you can easily see the pixelation. I have transferred some old VHS tapes of animations we had to DVD using the pioneer desktop recorder set to the 2 hour mode. They have large areas of consistent colors that when move quickly show the problem real good. You do not see it even in the VHS tape. So I have ended up putting critical things on DV tape and having everything on DVD that we usually with view and pass around so the tape can be stored and protected.
