I have a Plextor PX 708A (internal IDE), plenty of disk space and memory, fairly fast sytem, etc. I have a Philips 642 DVD player, the one that supposedly plays everything.
I mainly use the latest version of Nero, along with DVD shrink, DVD decryptor. When I burn the movies, I always do a verify after recording. But some of my movies keep stalling for several seconds during playback on the Philips player. It usually doesn't do this playing on the Plextor.
I try to use decent media. Some of the especially bad ones were Prodisk (MCC 02RG20), which has also made very good recordings, Ritek G04, which has likewise made a fairly good recording.
I'm wondering if it's a media quality problem, or a media mismatch, or possibly something software related in the re-encoding. I normally don't have problems with prerecorded DVDs, although once or twice I've had slight pauses or audio skips.
I'd buy a better player if I knew that was the problem, although I've heard that the cheap players often work better.
