I've just started playing around with recording OTA tv. Movie playback is working great. TV's are dialed in and razor sharp.

I had MP record for or 5 programs yesterday. All had the audio just a ms off. Also, I noticed on Heros which as a true HD program, had a real jerkiness about every 4 or 5 seconds. Sound was off here.

Do I have a CODEC issue or something? I'm running the latest ATI drivers and a HD show I copied over from my HD Tivo plays perfectly. It's something to do with the recording or the avermedia card.

Ideas?
