[mythtv-users] X Freezes blank on 'watch tv'

Wed Sep 29 11:11:50 EDT 2004

This is my first post so let me start by thanking everyone who has put 
in countless hours into this project.  While my setup isn't quite 
working (yet), I am so far very impressed.

I am just putting together my first Myth box by following Jarod's guide 
on FC2.  The TV card being used is a PVR-350 and as it turns out it is 
one with the 'new' tuner type (47).  Basically, I suffered the same 
problem detailed here (nothing but snow from the tuner)...

http://www.gossamer-threads.com/lists/mythtv/users/85687#85687

I then upgraded my video4linux module...

root at gwenno:~# rpm -q kernel-module-video4linux-$MYKERNEL
kernel-module-video4linux-2.6.8-1.521-20040922_114711-48.rhfc2.at

This gave me the video I wanted to see, but I still do not have any 
sound coming from the tuner.  From what I gather from this list, this 
has something to do with the msp3400 module not being up to date in the 
video4linux RPM above.  I don't quite understand how this all works, so 
bear with me.  In short, I get this error:

kernel: msp3400: Unknown symbol msleep_interruptible

At this point Myth is working, except for the sound issue.  I decided 
yesterday to compile the IVTV drivers from source to see if I could get 
everything working.  I downloaded this file:

ivtv-0.1.10-pre2-ck113e.tgz

Everything compiled and installed.  And, it looks like the modules are 
loading properly (output from the logs are attached).  When I try and 
watch TV from mplayer everything is working fine.

$ mplayer /dev/video0

I can watch TV in either a window, or in fullscreen with audio.

In MythTV, however, it is quite a different story.  If I choose 'watch 
TV' I get a blank screen.  The audio is working, as I can hear the same 
channel that was in mplayer.  Using the remote, I can also change 
channels.  The screen remains blank though.  After several seconds the 
remote becomes unresponsive as well, and the audio will fail.

X, at this point, is basically frozen.  Running top from an SSH session 
on a different machine shows me that X is at 99% CPU usage.  The only 
way to regain control of the machine at this point is to 'kill -9' X.

Attached are the logs from the frontend, backend and from the IVTV 
module initialization sequence from /var/log/messages.

If anyone could provide a hint of what I'm doing wrong, it would be very 
much appreciated.

Thanks,
Darren
