I pre-tune with tzap as sometimes my grabber is on different hardware.
Then run

~/bin/mhegepgsnoop-0.7.0.py -o /tmp/epg.test   -z -f ~/mheg.list -d 
"/dev/dvb/adapter${DVBT_CARD}/demux0" -c

Due to your logic I get an error connecting to MythTV's database

Getting channel info from MythTV database using mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using
password: NO)
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using
password: NO)

        if py_bind:
                # Get database channel info using Python bindings


        else:
                # Get database channel info from mysql

I don't want/need either option.
