I have power DVD deluxe version 6, and windows media player, i never had a problem with this before. when i was having problems with it, it did work once, the video did come up and exited out of the program and try to go back and see if it worked and it didn't work. I didnt download any new codecs or anything i dont understand why this is happening. it also doesnt work in windows media player ( it did ). the audio works great and no problem but no video which is weird, no message comes up at all for an error. i made sure everythign was up to date and that the driver was working correctly , the video settings have been the same and work fine, when I play videos that I downloaded they work but not the DVD's. any help please???
