I had exactly the same problem with FC3, I fixed it by using the TV out on the PVR 350 *BEFORE* loading the ivtv-fb module.
I did this by writing a ivtv startup script that loaded ivtv, changed the channel (I found the driver errored lots if I didn't) then did a dd if=/dev/video0 of=/dev/video16 bs=64k then killing it after 5 sec. To be honest though I've given up on FC3, went to SuSE9.1[1] and haven't looked back :-) HTH David [1] More grief in theory (ivtv and mythtv aren't in any of the suse apt sources I found for example) but I got a fully working stable (so far) mythtv box in about 10 hours[2]. [2] Aka 9 hours of downloading and compiling, one hour of work[3] :-) [3] In fairness this would have been *much* longer if I hadn't already built a FC2 and FC3 version on the same hardware. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of > John Harvey > Sent: 05 January 2005 21:14 > To: [email protected] > Subject: RE: [ivtv-devel] Fedora Core 3 > > > I don't believe it's the x-driver.
