[mythtv-users] MythTV can't (safely) record UK Channel five

[John Winters]

I've found an oddity on a new MythTV box which I'm in the process of 
setting up.  It's been working apparently perfectly well for several 
weeks, but then I discovered yesterday that the MythTV backend process 
silently crashes each time I attempt to record anything from Channel five.

Looking back over the programs recorded already (it's filled 150G of 
disc since I started it going) I found that this is the first time I've 
attempted to record Channel five.

The symptoms are that it will start recording then after 10 to 15 mins 
mythtv-backend silently exits.  No log messages, no error messages, 
nothing.  What it's recorded so far of the program is perfect, but 
obviously the recording ends (along with any others going on at the same 
time) as soon as mythtv-backend crashes.  As long as I don't record 
anything from channel five it's 100% stable and has been running like 
that for weeks.

Tuners are 2 DVB-T tuners, Compro DVB-T200.  The underlying Linux 
distribution is Debian Sarge, running kernel 2.6.17.  The processors are 
2 x 450MHz PIIs with 512MB of RAM.  It copes very happily with 2 
simultaneous DVB-T recordings with barely perceptible load.  It's purely 
used as a back end so playback isn't an issue.

Can anyone give me any suggestions on where I might start to look?

TIA,
John
