I'm recording OTA HDTV with a PC HD-3000 card.

The video quality looks perfect, rarely pixelates, but the audio is very bad: it sounds choppy, echos frequently, and has a pulsing quality to it.

I'm recording on a P3 1.6 with 768 MB RAM. From what I understand, recording OTA HDTV doesn't take a lot of resources because the card is just capturing the (already encoded) MPEG2 stream from within the ATSC broadcast.

I think the problem does lay in the capture side though because even if I transcode a captured show to xvid using nuvexport, the audio still sounds the same on playback and I think those transcoded formats wouldn't tax the CPU enough to cause audio problems.

Any ideas?
