Not really m8 it's dead easy. The box runs through a basic setup after you boot it for the first time or flash a new image.
It sets up things like network,tuner config etc then you just ftp you channel list and cline over and your done.
I actualy fecked my tm800 up yesterday i ftp'd to the wrong place so it wouldn't boot. I had it reflashed,channel list,cline all done within 15 mins and i was watching tv again now that's fast lol.
