I don't really know if this is the right forum for this question. But I give it a try

I have a NEC 2510 DVD burner and a Samsung DVD Player. When I ripp a normal original DVD movie that plays fine on the Samsung Player.

BUT when I convert a DivX/AVI to DVD it plays so bad on the Samsung. Every 10 sec it gets a bit blocky. But playing the same DVD on the Computer (NEC DVD) it plays just fine.

I tried to make the convertion both with ffmpeg and mpeg2works so I don't think it's the actual convertion it self??

Some ideas
