m17x - Can't play DVDs anymore

I just upgraded my sound driver and installed Service Pack 2 for Vista, but for some reason now my machine can't play DVDs.

It can install games from DVDs still, though, which tells me that (thankfully), the DVD player itself must be fine.

On Windows Media Player, the DVD drive just clicks and whirs while WMP seems to try to play each Title on the DVD, but only shows 1 frame from it and then skips to the next Title.

On PowerDVD8, the video shows up, but it's strangely slowed about 4x and there's no audio.

Can anyone please help me with this?? Thanks!

EDIT: When installing games, my drive actually sounds different now, sort of like a DJ scratching a record over and over again.

EDIT2: Wow, more has been screwed up than I thought. For some reason, the sound on almost everything is choppy (including Unreal Tournament 3). The strange thing is, I played this after I updated both and it was fine; it was only after I tried to do DVD playback that all this started happening. iTunes won't play music now; even if I hit play, the music does not progress. The VLC media player plays my DVDs, but with no audio. Can someone help me?? I have no clue what's wrong with this thing, and it just keeps getting worse somehow.

 

Hey,

Are you using bitdefender 2010. I had the same issue with DVD's and Blu-ray's. If it's the case, here's the fix: http://forum.bitdefender.com/index.php?showtopic=15350

 

I'd also say:

Reinstall all your drivers (uninstall, restart, install)

try VLC (videolan.org)

 

Heck ya, VLC rocks!

I installed SP2 without any problems, so not sure what happened. DVDs play fine, in both my BR-ROM and virtual drive....
