There definitely is a problem. Lots of transponders on hotbird have weirdy 
symbol rates. None of the ones about 5MBaud and below work with my patch.

However, tuning to ones with rates == 27.5MBaud actually seems much faster 
now.

Hmm, actually I've just noticed a channel at 22MBaud ain't working either. Now 
THAT is probably my problem.

(This is on a card directly connected to a dish BTW; the machine on the 
distribution system is still currently inaccessible to me)
