Changing that had no effect. 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. -- Gruß Andreas
