RE: [gentoo-user] OT - Need help getting MythTV to work with new(er) kernel

[Rik van de Bovenkamp]

Hi,

If you check dmesg, is everything OK loading ivtv?
You should see the ivtv messages between two ======== lines.
Using diff to compare the dmesg output for different kernels has led me to getting things to work.

When you do a ivtv-tune -f xxx.xx   to set frequency.
After that cat /dev/video0 > test.mpg and you playback test.mpg is that OK (or you do mplayer /dev/video0)

Subject: [gentoo-user] OT - Need help getting MythTV to work with new(er) kernel

I had MythTV working perfectly with linux-2.6.14-gentoo-r5.  I've tried
to upgrade to linux-2.6.15-gentoo-r1 using genkernel and basing the
newer kernel's configuration off of the older one.  I've booted with the
new kernel, remerged ivtv and rebooted again with the new kernel, but
still I cannot watch LiveTV in mythfrontend.  Here's the output of
mythbackend.log:

camille ~ # cat /var/log/mythtv/mythbackend.log
Starting up as the master server.

It is current (I stopped mythbackend, deleted the old mythbackend.log,
restarted syslog-ng and then mythbackend.)  When I start mythfrontend
and ask to watch LiveTV, all I see is the blank screen.  Here is the
output of running mythfrontend from my terminal:

I see there:

mythtv: could not connect to socket
mythtv: No such file or directory

But mythbackend IS running; from another teminal tab I issue this:

I would post the new kernel config, but since it's based off the old
kernel config, and the old one worked, I don't see the necessity.  I
will post it if it would be helpful.  Why is this not working?  Have I
forgotten something?
