Skipping / jerky DVD DTS audio on Audigy 2 ZS also crash when using Media Source DVD-A pla

Question

I've been having a difficult time playing 5. DVD audio using my new Audigy 2 ZS card. I have updated drivers from Creative.
When I try to play the DTS track on a DVD-A (e.g. Queen's "A Night at the Opera"), I get choppy skipping sound -- the music sounds good, but it skips and is jerky. The PCM 2-channel stereo on the same disc sounds fine. Dolby Surround on another DVD-A disk (not DTS), "Trey Anastasio" also starts out jerky and skippy, but then seems to "settle down" in the middle of the first track. The Creative Mediasource DVD-A player doesn't work at all on-- as soon as it launches, it crashes and reboots my computer (which suggests to me that it must be some driver conflict issue or something). That problem only happens when playing certain discs -- e.g. the Queen disk and the
DVD-A of Yes' "Fragile."
I have installed on my system Windows Media Player 0, WinDVD 4 (OEM), Nero Showtime and Creative's Media Source DVD-A player.
I am using a brand-new HP Pavilion a730n Windows XP SP2 52Mb RAM.
DVD player is Lite-ON DVD/RW SOHW-832S
Video card is nVidia GeForce 6600
Any suggestions?
Thanks.

Answer 1

ok, I normally use powerdvd 6, now with dts 96/24 decoding pack, and I have the latest patch to version 47 installed.
it is the same again: when using 6 speakers in audio configuration menu, queen dvd plays perfectly, when using spdif output and decoding via zs card, sound is distorted. I noticed that if I activate "show information" in powerdvd, detected sound track changes between "dts 5.0" and "dts 5. 96/24" all the time in spdif mode.
is there a problem with powerdvd AND windvd or the audigy2 zs ?
