I have Win XP Home, Powerdvd 4 with 6 speaker option, Creative Audigy soundcard set to 5.1. When i try to play a dvd the sound stutters very badly. It works fine when I set Powerdvd to 2 speakers but again stutters on 4 and 6 speaker settings. I have uninstalled both Powerdvd and soundcard drivers, reinstalled both but still the sound stutters. Any help would be greatly appreciated.

What type of speakers? Klipsch? Cambridge? The Audigy has a diagnostic, when you set the speaker set-up, there should be the "test speaker" option. Also, how fast is your CPU? how much RAM do you have? One cause could be, since 5.1 channel takes much more processing power than simple 2 channel.

Speakers are Creative Inspire 5300 5.1 surround, running an Athlon 2100XP processor with 512mb ram. Have ran diagnostic and speakers test ok which seems to suggest that the problem may lie somewhere between the LG DVD Drive to the soundcard to the speakers !!! Any suggestions would be worth a try

Another thing to do is disable any onboard (integrated) sound card in the CMOS Setup which could conflict with the Audigy card.

I had the same problem with my Audigy Platinum and Klipsch 5.1 speakers when I first got my new PC. I carefully went through the settings for the sound card and also Power DVD 4.0. If I remember correctly it was a wrong setting in PowerDVD that caused it. I'm sorry, but I can't remember which one it was.

if the integrated sound card wasn't disabled in the first place, the audigy would not be working at all. two things to consider: simplest, try a different playback software, second, see how many programs are running in the background, as 5.1 channel needs a lot of processing, a ton of background porgrams will slow the rendering.

still no go. Have closed all background programs, have tried Windvd 3 also but still no joy. Have even un/reinstalled driver & creative software. Could it possibly be a graphic card driver problem ? Could it be a faulty soundcard ? I really do not know what to try next
