Weird. I have only had problems with the frequencies below 100 MHz (I am unable to confirm problems from 91.25 to 115.25 as I do not have any signals on cable channels 95-99.) I planned on experimenting with the board this weekend but wound up not getting around to it. :( Also, anyone posting here needs to define the degree of the problem, i.e. whether it is "there's a little static, I can notice it and i'm being picky", or "so bad it's barely watchable" (Such as from the MPEG clips posted a week or so ago which had the EXACT same symptoms on tuner 1 lowband that I did.) After living with OTA broadcast TV for three years, I don't notice mild static on cable channels, as it's far better than what I used to have to deal with. I'll admit, while I plan on experimenting this weekend, I'm sort of afraid to do so since my card decided to start behaving properly for no apparent reason at all 3-4 weeks ago. :) That's going to make this problem extra hard to solve - intermittent problems or ones that fix themselves after a period of time are the hardest ones to fix. :( _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
