Hi
I had been having trouble getting sound under winXP when streaming live TV from my PVR-350. The video would display fine, but I would always get no audio (locally and on clients).
I finally found a solution with a program called wintv source selector. You can get it here:
ftp://ftp.shspvr.com/download/wintv_sou ... .22266.exe
This program lets you select the audio source. I set it from "CD passthru" to "TV Audio" and all my troubles were solved.
Hope this works for all you out there who I saw were having the same problem.
