perhaps Windows Media Player. You may have a funky DVD.
I did a clean install of Xp Home edition with SP2 and current updates and applications. There were no problems until I went to use the DVD playback feature in Nero Suite (Nero Showtime) the program had sound only, no video and after a few minutes it froze. The event log said ''Win XP error hanging App''. Why is this happening?? Is it another one of those Unknown error things with windows Xp? Any advice is appreciated.
