[mythtv-users] UPnP with a PS3 questions

[Daniel Smith]

I have a backend with a Hauppaugge pvr mpeg2 encoder and a pcHDTV 5000 
digital recorder. The backend is running Ubuntu 7.10 with Mythtv .20.2 
on it. (I was using SVN for a while, but I found more problems than 
benefits.) Please let me know if there is any other hardware info that 
could be useful.

I can connect to the backend from my PS3 using UPnP on the XMB (without 
Linux) and I can play files recorded with the mpeg2 tuner fine. Anything 
that was recorded with the pcHDTV would not play audio (Sony doesn't 
support AC/3 audio in a transport stream) and anything transcoded to nuv 
will not play at all. So I created a User Job to clip the commercials 
and save the file as an mpeg2 program stream using this:

mythtranscode -c %CHANID% -s %STARTTIME% -p autodetect -m -e dvd -l; mv 
%DIR%/%FILE%.tmp %DIR%/%FILE%; mythcommflag -c %CHANID% -s %STARTTIME% 
--rebuild --clearcutlist

I can use this for recordings from both tuners but playback is not 
reliable on the PS3. First off, the files take about 30 seconds to a 
minute to start playing and the backend will utilize a CPU to 100% on 
the server. If I let the program play to the end (ff, rew and pause work 
fine) then I can usually start another with no problem.

However, if I stop it and start a different recording thats been 
reencoded this way than the backend will max out both CPUs and I get a 
network error on the frontend. I will also get the same network error at 
random times anyway. Also the Mythtv status on port 6544 no longer works 
from any machine, however recordings still play fine from a frontend or 
xbmcmyth. Restarting the backend will fix the network error, but it 
shows up again in the exact same way.

Is there something I'm missing or some other info that might be helpful 
that I can include? Does anyone know how to fix this to get playback 
working properly through the UPnP? If there anything else I can try or 
some way I can help with fixing it, please let me know

Thank you,
