[mythtv-users] Unable to change channels and no audio

[aslong at uark.edu]

Ok, new problem.  And it's a biggie.

I cannot change channels on live TV. It just gives me something that says "(O minutes)" in the OSD that appears.  Similarly, there is no sound.

This is what I have confirmed:

1) Sound DOES work.  I can play test sounds and sound in playback.
2) I am using the keyboard, not a remote at the moment.
3) I have dumped my entire mythconverg database and run mythfill database again.
4) I have also just rebuilt FC3 (Kernel 2.6.10-1.741_FC3) today and was able to completely duplicate the problem.

Now, I can get everything to work find by manually killing mythbackend and restarting it after I get into KDE.  If I manually do it, sound works, channels change, and life is good.  But, I can't automate it.  I have tried the following in my /etc/rc.d/rc.local

-------START------------
/sbin/service mythbackend stop
/sbin/service mythbackend start
-------END------------

the above didn't work, so I tried just

-------START------------
/sbin/service mythbackend restart
-------END--------------

It didn't work either.

I have also subsituted "/etc/init.d" for "/sbin/service" in the above statements, and it didn't work either.

I guess what I am basically hoping for is for advice on some way that I can automatically restart mythbackend when the autologin for my mythtv user launches KDE, or, better yet, an explanation of why this is happening.

Here is the output I get at the console when I run mythfrontend.  I am particularly concerned by the "QDateTime::fromString: Parameter out of range" error that is showing up.  Any help at all would be greatly appreciated.
