I have the same problem with 2 successive DVD drives,
ASUS DRW-1814BLT - installed first, then a few months later
TSSTcorp CDDVDW SH-S203N
Both suffer the same problem - namely freezing on video playback, or stuttering - this is both on commercial dvds and ones generated/initialised from a dvd recorder attached to tv.
I’m using windvd as the player software, and there is no difference if played through WMP.
Can any one point me towards a solution ?
