Pixelating DVDs, any ideas?

[mudbug162]

After burning 4 AVI movies to a dvd from my computer, 2 of the movies are pixelated when i play them in my dvd player. I burn them using DivX Player onto a 4.7gb disc and my dvd player is divx compatible, so why does two out of the 4 movies end up pixelated and not all of them or none of them? I check each one on the computer before burning and all work perfect. Theres nothing worse then sitting down to watch a movie and its all messed up!

Possably some of the videos were not full size?
PAL standard definition is 720x576 (for 4:3 or widescreen). if they were only 640x480 (for example) then they would be stretched to fit your TV.
Or if the picture is "blocky", this is usually due to high compression on the video. Your PC may handle the compression codecs and bit rates better than your DVD player.
