[mythtv-users] PVR-500 Audio glitching

[Norm Dugas]

I'm not really sure how to describe the issue I'm seeing (hearing) other 
than to call it audio glitching.  I thought I'd ask here to see if 
anyone else has experienced this with a PVR-500.  The best way I could 
describe it is that while audio is playing, you sometimes hear some 
strange squealing.  It's like the audio speeds up for a moment but not 
really.  At first, I thought it was the audio on my FE but when I heard 
the same sound at the same spots on a 2nd FE, I was sure it was the 
source.  Next, I listened to the raw recording (pulled it out using 
Nuvexport) and it was there too.  I've gone through the mythbackend logs 
and any other log I can think of but I don't see any errors.  What's 
interesting is that it's not consistent.  Maybe it's tied to one of the 
tuners?  How can I tell which tuner recorded a program?

Backend:
Asus P5LD2 Deluxe
Intel Pentium D (don't remember which but each core is at 2.8 G)
2 Gig memory
Hauppauge PVR-500
2x Samsung 1T SATA drives
4x Seagate 420G ATA drives
Running Mythbuntu 8.04

Thanks,
