No audio on recordings

[oneglory]

GB-PVR newbie and I'm starting to have this problem with no audio on the recorded programs.

Rig:
Hp A643n
2.0ghz AMD Athlon 64 3400+
1gig ram
ATI Radeon 9800 Pro 128mb (DVI to HDMI)
VisionTek ATI 550 Pro
DVD/CD R/RW
Windows XP Pro SP2


Now I had GBPVR and the 550 Pro in a dell optiplex 240 before and didn't have this problem.

Sound is fine in everything but the recordings?

Can you play the recordings in another program? e.g. WMP or VLC.
Have you tried changing your audio decoder/renderer in config?
