That was intentional as I was using a HVR3000, and it is a dual DVB tuner.

I've reconfigured myth to not release the tuner when it has finished and 
also tried to use the Nova-T500 that I have as well, this is what I get 
in that case


[root at server neil]# /home/neil/mhegepgsnoop-0.3.6.py -m "-u<user> -p 
<pw>"  -d /dev/dvb/adapter3/demux0 -o /home/neil/mheg.xml
Traceback (most recent call last):

     the_pid = find_pid3(dmxfd, demux_filter)

     program_info_len =((buf[10] & 0x0F) << 8) | buf[11]
IndexError: list index out of range

I do however get something in the output though, so something is happening.

So you can successfully run this while recordings are taking place?

I'm going to have to try to find some time to dedicate to working on 
this to get it working correctly.
