what do other programs do when they are run ?
have you tried in safe, ,,,putting in the dvd ?
in windows explorer , go to tools , folder opts , file type ,,,,scroll down to the VOB file type ...see what is associated with opeing the vob files on your dvd, should be a dvd player.
I use Power DVD. When i play a DVD the program ends up "not responding". When the blue screen comes up again i shall make note. I havn't tryed safe mode yet. will do.
I have updated all the drivers for my motherboard and also the firmware for the dvd rewriter. This DVD rewriter worked fine in my old pc. I put in an older DVD ROM drive BUT even that dont work when i try to play dvds..... I am thinking, could my motherboard be broken or something??
