[mythtv-users] mythtv install: capture card setup, failed to open

[Roger Biffiger]

Hi there

I am trying to install mythtv frontend on beech and mythtv backend on larch.
I am struggling setting up the (master) backend on larch.
I am using a Hauppauge WinTV PVR-350 analog tv card as a capture card.

roger at larch:~$ uname -a
Linux larch 2.6.32-24-generic #41-Ubuntu SMP Thu Aug 19 01:12:52 UTC 2010
i686 GNU/Linux

roger at larch:~$ mythbackend --version
Please include all output in bug reports.

using_ffmpeg_threads using_libavc_5_3 using_live using_mheg

When I run mythtv-setup and go to "2. Capture cards" to add a new capture
card, I am not sure what Card Type to use.
Shall I use "Analog V4L capture card" or shall use "IVTV MPEG-2 encoder
card"?

When I choose "Analog V4L capture card" and add "Video
device"="/dev/video0", I get "Probed info"="Failed to open".
When I choose "IVTV MPEG-2 encoder card" and add "Video
device"="/dev/video0", I get "Probed info"="Failed to open".

roger at larch:~$ ll /dev | grep video0

roger at larch:~$ grep video /etc/group

roger at larch:~$ cat /dev/video0 > tmp.mpg
cat: /dev/video0: Permission denied

I don't know how to tackle the problem. Any ideas?

Thanks
