Then after about 10 seconds it's fine and the Dolby Digital logo flashes up on the screen.
It's as if the sound card is having difficulty "locking onto" the stream.

It's not the DVD drive or even the computer because it did this on the old Athlon 3200 system I had.
The only things the same are the sound card, the OS (WinXP Pro), the DVD software decoder (PowerDVD XP) and the graphics card manufacturer (Radeon).
I ran a 9600XT on the old system and a 9800 Pro on this one but I still get the same problems and it also happens in Media Player, WinDVD and PowerDVD.

Has anyone else had this problem or do you know what's wrong?

If I watch a movie encoded in DTS I have no problems, which is cool because DTS sounds better anyway but about half of my DVDs are in crappy Dolby Digital.
I've got a DTS amp downstairs, it's sounds exactly the same as Dolby Digital and from what I've been looking at on Google, pretty much everyone say's the same, "the difference is negligable".

Anyhoo, try uninstalling your creative drivers, then run driver cleaner to make sure they're ALL gone, reinstall the original's from the CD then update from creative's site.

Alternatively, enable your onboard sound (if it's got a digital out) try it using that instead of your Audigy (make sure it's set to use it in the control panel etc too)
