I'm also having trouble getting this board to tune to 536625000 Hz, have
tried all different combinations of frequency offsets with no luck. 
Running the latest v4l-dvb tree pulled from linuxtv.org about 30 minutes
ago.  Running kernel 2.6.17-1.2174_FC5.

What other info do you need?

Oh, this board uses the Zarlink 10353 frontend, not the MT352, is that
relevant?
