"scratchy" distorted sound HELP - URGENT!

[RichardH]

Daughter's got a load of mates round tonight for a big film watch and sleep over, and the sound's gone mad on the HCPC. I will be DEAD if I can't sort this soon!!

Running MAudio 410 as analogue sound card, with WinDVD 4 doing the decoding.
Already watched 2 films today - fine. Started up another, and the sound's coming out very strangely - almost skipping and jumping stuff. Tried different DVDs, then also a CD (also played throught WinDVD) - all the same. So Tried playing CD through Media Player - also the same. Then ran an .MOV from the HD, and it was fine.

So it looks like it's something to do with the DVD drive/signal from it. I guess the other thing to try would be to rip a DVD to HD and try it from there, but that will be new territory foir me, so I'll have a look around. In the meantime, any suggestions?

Has DMA been disabled for that drive ?

[RichardH]

Well, I have XPHome on that PC, and don't know it that well TBH. The onbly place I can seem to set the DMA is against the disc controller, and I have it set to DMA if available.
I just ripped a disc to HD with DVD Decryptor, and it worked fine, so it certainly looks like it's a DVDRom thang. I might try swapping out the DVD Drive for another one and see what happens then....

[RichardH]

Well, a different DVD ROM did the trick, so my skin is saved....

my heart was racing and I almost broke into a sweat!

Glad you got it sorted!

Hope they enjoy the movie.

Thanks for the help all. I'm so glad I'm an anorak who has multiple computers scattered around the house - though my wife took one look at her now stripped pc and wailed "my computer!!".

I tell you, I have never seen so much chocolate and junk consumed in one night, but it looks like they all enjoyed themselves (heh heh - went in to check they were all OK, and one girl piped up "do they both get out alive?" in a quivering voice - the power of cinema!).

Now to fix my wife's PC....
