I have a Creative Zen vision W and use Clonemobile DVD with Any DVD to add DVD's to my player. I have noticed the video can seem a bit choppy or stutter at times and the black backgrounds can look pixilated. I was wondering if its just how the player plays the converted video or if I could use a different format and get a smother result. I have tried different qualities and get the same result. This is with every DVD I have converted. The movies are watchable and I think it might have to do with the player. Maybe its processor is a bit on the slow side? or because its playing it off a hard drive instead of a disk? Any help would be appreciated.
