Why such a complicated setup?

It seems like the frontend is trying to access the LiveTV ringbuffer in 
/var/lib/mythtv/recordings, rather than wherever else you've got it 
symlinked to. Can you verify that the user the frontend runs as can read 
files from /var/lib/mythtv/recordings?


The symlinking idea is a new one which I was trying out to try and make 
it easier to reinstall everything if I have to in the future.  The 
recordings are on a separate XFS partition.  I tried pointing the 
mythbackend directly at this directory.  It allows playback of existing 
recordings but doesn't improve the current problem.

Yeah I downgraded to Intrepid because I was sure that something in the 
upgrade to Jaunty caused this problem.  Unfortunately I was stupid 
enough to allow all the available updates after downgrading so my 
efforts were probably wasted (symptom of coming from the world of 
Windoze where updates are critical).  Oh well learnt something about 
backing up and restoring mysql DBs!  Aaron, how easy is it for you to 
try a reinstall?

I think that there has been an increase in the time its taking to change 
channels.  So it may be the backend is taking longer to tune and add the 
recording.

Another thing that may be a factor is what system you are running.  
There was some allusion to the fact that these problems my be isolated 
to AMD_64 users of which I am one.  What version are you using Aaron and 
for others who have this card what versions are you running?
