That might be the problem.  I'm pretty sure that the stoth drivers only
work up to kernel 2.6.18 - unless there is another patch that I've not
seen.

I think the only gotcha is that it registers, one card with two frontends
and Myth doesn't support this, so I had to symlink the 2nd frontend to a
"fake" 2nd card and then it worked.

I think so.  I get as many channels as I do on my (non-sky) set-top box. 
BBC1..4, ITV1..4, Film4, Men & Motors, BBCHD, News24, plus loads of others
that I don't really watch.

If there are some I'm missing I'd like to know about it ;-)
