I am capturing TV3 (AC-3) shows using a Hauppauge HVR900H using gbpvr. Works pretty well. I am using an external UHF antenna and when gbpvr tunes the channels, signal strength is strong.

But occasionally when viewing the recorded shows, a burst of static noise will occur in the signal lasting a second or so. This is on the DD track. It's pretty loud! Seems strange given the strength of the signal I am getting. Wonder if anybody else has experienced this?

While annoying it also makes re-encoding the shows into smaller files almost impossible since the programs I use to mux the audio back to recompressed video detect this static as bad data in the AC-3 stream and delete it. This causes the audio to go out of sync with the video.
