Radio station in background during recording?

[spadesmaster]

I have a Haupaugge WinPVR USB2 (their latest which includes a radio) and Beyond TV 3.3 and I have the wierdest problem:

I get a radio station in the background during playback of PBS recorded shows. I get the main TV audio too, just the radio is in the background as well.

What I have tried:
1) Only appears to happen on PBS shows (Sesame Street is the main one I have been recording)
2) Happens on BOTH of our PBS stations.
3) Doesnt happen on Live TV.
4) Didnt happen with my WinTV PVR-250 card which I used to use with Snapstream (I switched to the USB to get rid of the interference, which it did nicely).

I have no interest in EVER using the FM features on the WinTV PVR and would be happy to just disable them, but I cant seem to find any preference or options, even under WinTV 2000.

Any ideas? Im baffled and my poor daughter wants to watch Sesame Street!

Do your power cords wrap around the video/computer cables? That'll cause interference like that in a heartbeat.

No, the main reason I went to the USB PVR was to get rid of the RF interference. I have no interference and very clean audio and video on every channel, while watching live TV, the FM radio overlay problem is ONLY while recording and ONLY on PBS for some reason.

I strongly suspect the Hauppauge unit is somehow mixing the audio from the FM tuner in with the TV for some reason. Everything else is clear, just this second audio track...

I have exacly the same problem with my WinTv USB2. After listning to the WinRadio, when I go back to the BTV the screen turns black, changing channels doesnt do anything and all I can hear is the radio, and not even the same FM-channel i listened to earlier. I have to restart my computer to get the LiveTV on BTV 3.4 to work again. No scheduled recordings will work without a restart either.

Anyone knows a solution for this annoying problem?
