DVDs not playing correctly

Right i have a new computer (bought in September) Its a compaq presario with a Proview TFT 17inch monitor with built in speakers. I've just moved to university so before had no reason to play DVD's on my PC. But when i try and play DVD's the sound sort of staggers and isn't fluent its like its playing while buffering, jittery i guess. I don't know why, its not the dvd as i've tried loads of different ones nor the player as it does the same in media player, real player and intervideo.

Is it my built in speakers just being crappy? Or what?

 

Have you got the Latest Sound Card drivers, Codecs and DirectX installed?
Also in WinDVD, make sure your sound and video options look like these >

I'm not sure how do i tell? In the 2nd gif the top two boxes were ticked so i unticked them but no difference.

 

You can find them in dxdiag, click start > run > dxdiag

In that case everything is up-to-date

 

I don't know if it means anything but when i put the dvd in the computer becomes very noisy

 

No thats just the DVD drive spinning the disc. If it is very unusually noisy then make sure that the disc isn't damaged as small fragments on it can cause destabilizing when inside the drive.

If all else fails, try using a different sound card in it to see if it still has the same problem.

 

Also check you ahve nothing else running in that background when you try to play your dvd this can sometimes cause lag

 

Something else i've noticed is that the playback is slightly staggered for the video too and if you try and move the window in which the dvd is playing around the screen its slow to respond..

 

What CPU and Video Card are you using?

 

ATI Radeon Xpress 200 series graphics/video card
2.2-GHz Athlon 64 3200+

 

I have had a look around and this it may be something to do with DMA.

Do these screen shots mean anything to anyone?:

 

In your secondary IDE channel, it is using PIO instead of DMA. PIO is terrible. Try setting it to DMA manually (Windows will demand a reboot). Once you're back up again, you should have full DMA on that channel.

How do i manually change it? Thanks by the way

 

Just click on the transfer mode menu and reiterate your DMA selection. That should do the trick.

 

Thanks mate it didn't exactly work but using your help i managed to track down an article which did the trick:

So now i have lovely smooth playback and i can watch DVD's at long last! I recomend the Blues Brothers by the way!

 

Usually you can choose PIO, exit, then choose DMA again, reboot, and it works. But either way, glad you got it working.

All the best,

P.S. - Yeah, Blues Brothers rocks! "We're on a mission from God!"

 

Yeah i tried that but it didn't work, but never mind eh. Glad you agree about the BB's!
