Yes, I think it was Stephen W who pointed out to me that if you don't 
tell mythtv to release channels when it is not recording they stay 
locked and hence available for other code like mhegepgsnoop to read 
from. I forget the exact option which keeps the channel locked. 
Something to do with EIT maybe?

Turns out 'a' (as shown in your sql dump) is the default value for 
inversion and (I think) means 'auto'. I think this needs to be converted 
to an unsigned int with a value of 2 before it gets sent to your tuner 
card however I need to check/test this.

It hadn't occurred to me that channum might not be unique. The chanid is 
unique but how does the user know what it is without going into 
mythbackend setup or mysql? Maybe that is OK for typical mythtv users. I 
need to think that through. Any suggestions welcomed. One kludge I 
thought of was to create a dummy channel with a unique channum which you 
only use for getting the epg. Sounds painful to set up.

I think the other problem you had with clean_titles2 is a bug. I tried 
to make the code work with the old optparse command line parser and the 
new argparse parser but I think I must have screwed up the clean titles 
bit. I will try and fix this also.

No promises about when I'll get this done. :)
