I put this in another group but might as well try here. My 1530 will stutter on dvd playback primarily with wmp. With vlc its at least watchable but still you detect a blip once in a great while. I dont know whether to blame the drive or something else. Totally unwatchable with WMP. It stutters every second. It went 15 minutes with wmp this morning and then started in every second. I have looked everywhere and dont know where else to turn for this one.
