[mythtvnz] Epgsnoop

[Nick & Ann Read]

This is probably me being dumb... but:

I was just experimenting with epgsnoop, and it appears to be able to 
pull down listings from the Sky transceiver, in spite of being tuned to 
the Freeview transceiver (watching TV3 to be sure it wasn't on Sky). How 
does it do that? The card can't tune to two transceivers at once, 
especially on different polarities, can it? The xmltv file has data for 
all the Sky channels, so can't be coming from Freeview. I didn't run 
dvbtune, just ran epgsnoop while watching TV3.

Explanations gladly received.
