Hi,

I've reinstalled the MythTV box, and suddenly I have this strange
problem. I have a PVR-350 card and a PVR-150 card in the box which are
set up like this:


mythtv at mythtv ~ $ echo "select * from capturecard;"|mysql -u mythtv
-pmythtv mythconverg |grep v4l
1       /dev/v4l/video0 NULL    NULL    MPEG    Tuner 0 NULL    mythtv
 0       0       0       1       8192    8192    0       0       NULL 
  0       2       0       NULL    0       0
2       /dev/v4l/video1 NULL    NULL    MPEG    Tuner 0 NULL    mythtv
 0       0       0       1       8192    8192    0       0       NULL 
  0       2       0       NULL    0       0

Now, as the unpriveldged user running mythfrontend, I may tune to a channel:
mythtv at mythtv ~ $ ptune.pl -c E7 -f pal-europe -d /dev/v4l/video0
Ch.E7: 189250 3028

This changes the channel correctly when watching TV using mythtv.

However, I cannot change channels using the remote or keyboard. There
is the usual small re-caching delay, but the channel is still the same
when the output comes up on the screen.

For debuging purposes, I have enabled all to write to the devices, so
this shouldn't be a permission thing:
ythtv at mythtv ~ $ ls -al /dev/v4l/*
crwxrwxrwx  1 root video 81,  64 Jan  1  1970 /dev/v4l/radio0
crwxrwxrwx  1 root video 81,  65 Jan  1  1970 /dev/v4l/radio1
crwxrwxrwx  1 root video 81, 224 Jan  1  1970 /dev/v4l/vbi0
crwxrwxrwx  1 root video 81, 225 Jan  1  1970 /dev/v4l/vbi1
crwxrwxrwx  1 root video 81, 228 Jan  1  1970 /dev/v4l/vbi4
crwxrwxrwx  1 root video 81, 232 Jan  1  1970 /dev/v4l/vbi8
crwxrwxrwx  1 root video 81,   0 Jan  1  1970 /dev/v4l/video0
crwxrwxrwx  1 root video 81,   1 Jan  1  1970 /dev/v4l/video1
crwxrwxrwx  1 root video 81,  16 Jan  1  1970 /dev/v4l/video16
crwxrwxrwx  1 root video 81,  24 Jan  1  1970 /dev/v4l/video24
crwxrwxrwx  1 root video 81,  25 Jan  1  1970 /dev/v4l/video25
crwxrwxrwx  1 root video 81,  32 Jan  1  1970 /dev/v4l/video32
crwxrwxrwx  1 root video 81,  33 Jan  1  1970 /dev/v4l/video33
crwxrwxrwx  1 root video 81,  48 Jan  1  1970 /dev/v4l/video48

What am I not thinking about????
