[mythtv-users] DVB Failing at same time each week!

[Dave Sexton]

Hi List,

	I have a repeating problem that started three weeks ago.

	I have two Hauppauge Nova-TD-500 dual tuner DVB-T cards, MythTV 0.25.2, 
Kernel 3.2.0 - Ubuntu 12.04 (Precise). Each tuner is configured to record up to  
two simultaneous streams.

	At 9PM on a Friday, I attempt to record "8 out of 10 cats" on Channel 4 
and "The Mentalist" on Channel 5. For the last three weeks (since the start of 
this series of the Mentalist), the entire DVB subsystem seems to hang. Myth 
stops being able to record anything, it fails to perform any action with the 
DVB cards. I get entries like th following in the logs :-

and lots of :

DVBRead mpeg/mpegstreamdata.cpp:362 (AssemblePSIP) Error: offset>181, pes 
length & current cannot be queried

When checking just minutes beforehand, the program listings are up to date and 
all tuners can tune to the required channels.

The only thing I can think of is that something is being transmitted at that 
time which is killing the DVB cards.

Is anyone else having this kind of problem?

TIA,

Dave
