Anyone have any ideas?
I was using my ATI Wonder frame grabber (TV card) right up until August
2004, under Fedora 2, without any problem. Then I moved and didn't get
cable, upgraded to Fedora 3, and never had need of it since. Then, 2 nights
ago, I wanted to make a copy of a videocassette and was not able to. After
many hours of fiddling and frustration, I made the copy in Windows, by
issuing a single one-touch recording click, to record the output of channel
3. Nevertheless, this is something I want to solve, so as not to have to
'resort' to measures in the future.
I believe my ATI Wonder is properly configured. I have the same modprobe
settings as I had under FC2 and the same as listed in the kernel
documentation. dmesg shows that the bttv is loaded as /dev/video0 and I have
a tuner=2, also properly recognized.
Nevertheless, tvtime fails to show any display at all. In kmplayer, when I
try to detect the device, it says no devices found. No difference if I
manually set it to /dev/video0. I have tried to directly access channel 3,
the one the video machine sends on, by issuing tv://3 in kplayer, mplayer,
kmplayer, videolan to no avail. I have tried to see whether the video
machine's channel 3 output appears on channel 3 in the television setting,
the composite, or the other one (is it svideo, or something). None work.
Just a blank screen.
Yet, when I use gnomemeeting or camE, I can get 'snow', like having a wrong
channel tuned. These programs do not have tuner capabilities, so I suspect
they might be reading what is coming off channel 1, although I could be
I have scoured the documentation, suspecting that something might have
changed from FC2 => FC3, but I have everything set as in the documentation,
as far as I can tell. I have the programs using v4l and xv, which I believe
is the preferred way. Are there other ways? But this always worked before.
