Which version of tv_grab_nz-py are you running? I seem to remember there 
being an issue with this on the earlier versions (or was that epgsnoop, 
I can't remember). Latest is 0.2.6 as far as I'm aware.

FWIW my epgsnoop+tv_grab_nz-py setup is working just fine. Using 
epgsnoop 0.84 and tv_grab_nz-py 0.2.4 (time I upgraded, heh!) so the 
system isn't broken for everyone, at least.
