Just to let you know that you're not alone:
I had a simiilar problem with the combination of an AverMedia A180 and 
two Asus Falcon (they use the ivtv drivers and firmware). Whenever one 
of the Falcons was recording, I got blips and dropouts on the 
AverMedia. I chalked it off to a flaky mainboard and seperated the 
Falcons and the Avermedia in two different computers. A while later I 
got a new mainboard and additional ATSC tuner cards. As long as I had 
two of the ATSC tuner cards installed, the recordings were ok, except 
for an occasional dropout. But when I put a third ATSC tuner in, the 
recordings were barely watchable. After I put two ATSC tuners (2x 
Avermedia A180) in a different computer, they *all* are recording 
almost perfectly. Even a HVR-1600 card that I had dismissed as broken, 
delivers very good recordings in the other computer.
