I've got another tuner which works, so I know I'm tuning correctly, it just
doesn't actually tune. I tried with mplayer, it just sat there saying
dvb_tune Freq: 219500000 and did nothing. It also made my whole
computer go really slow, I don't know what it was actually doing.

Antti, as I said I've never done anything like this before so I have no
idea what I'm doing, so I have no idea where to paste which table.

Jarryd.
