Windows 7: Issues playing HD video.

what's your gfx card ?

Asus Radeon HD 6770 1 GB.

The latest update on my utterly irritating situation: GOM Player (which played normal DVDs fine last night) no longer plays normal DVDs. When I try to play them, the player simply does nothing.

VLC Player has also developed an issue with normal DVDs, the sound blanks out for a second every few seconds, just like it does with HD DVDs.

WMP no longer plays normal DVDs, giving the following error message:

"Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card."

BS.Player simply won't open normal DVDs.

This is getting beyond a joke...

are you on 12.8 CCC ? else sound like a windows reinstalling or hardware issue to me.

I'm on 12.8 CCC. I'd rather not reinstall Windows unless I absolutely have to... what sort of hardware issues might there be? Might it be some fault with my GPU?

a GPU fault can be detected via running a latest Game.

What you could do is try one of the try before you pay video players. The one I like and ended up purchasing was Cyberlink's Power DVD HD. Power DVD will do dual layer DVD's along with Blu-ray Disc. There is also WinDVD from Corel (tried it but went with Power DVD). Just some Ideas. . .

Thanks for the advice. I'll give PowerDVD a go, I've downloaded the trial version.

I've just had a thought. Don't know if this is at all significant, but the problems with playback started after I'd played a Region 1 DVD on my PC. I didn't realise it was Region 1 until I looked at it just now, I bought it used at Money Station here in Scotland. The DVD played fine, and I watched half of it, on VLC Player. Then, when I tried to play it again later, it started repeatedly missing chunks of the audio at regular intervals. I think that's when the problem started. Before that, the only problem I'd had was with one HD DVD which wouldn't play on my PC, but that was the only HD DVD I'd ever tried and everything else worked okay.

Here's the latest:

PowerDVD isn't much good for me, because - although DVDs play fine - the picture is really pixelated with all DVDs. You don't get the quality of picture that VLC or GOM Player provide. Is this problem unique to me?

P.S. Evil Nemesis, I have Asus SmartDoctor on my PC which monitors my GPU constantly. It should flag up an issues with the card. Also, games seem to be playing fine - I can play Minecraft full-screen without any performance issues, apart from SmartDoctor warning me about the temperature of my GPU increasing from time to time.

Problem solved! I think. I downloaded a trial of AnyDVD, and now everything works on VLC! I don't know whether to buy it or not when the trial runs out though - will it continue to work?
