[mythtv-users] Mythbackend error on FC2 and/or FC3 and cx88

[Liivo Liivrand]

Hello All!
 
TV card is Leadtek TV2000 XP Expert (If i'm right it had Connexant 23881).
FC3 is up and running. Kernel module options are correct and working fine.
tvtime is working fine (although with not so good picture as it has under
windows, but the quality is still acceptable), so there is no conflicts
between FC3 kernel, modules, tv-card and v4l. Installed myth from fc3
atrpms, backend crashes with "segmentation fault" and no readable error
messages when choosing "Watch TV" from frontend. Also myth fc2 at.rpm-s
didn't work, entering to "Watch TV" gives only one frame with green and
white colors with very low resolution and then hangs forever, frontend
looses connection and had to kill manually backend. So, decided to compile
manually myth 0.16 from CVS. Compiling was successful. After manually
compiled mythtv I got finally some kind of readable error message. So the
symptoms are still the same. When choosing "Watch TV" from frontend, backend
gives inifinite count of message: 
VIDIOCMCAPTURE0: Invalid argument
VIDIOCMCAPTURE1: Invalid argument
...frontend looses connection and have to kill backend manually. Although it
is interesting that going to Mythphone live tv is showed in mythphone
window. But why it doesn't work in mythbackend ??? What is VIDIOCMCAPTURE0
and how to solve it?
 
This error is reproduceable using either FC2 or FC3.
 
rgds,
Liivo.
