Just a minor detail. The symbol rate being reported by dvbtune looks 
wrong, it says 525163520. I think dvbtune takes its input measured in 
Ksps, try 22000. Not sure if this will break anything (or fix anything 
for that matter).

I'm using v 0.5 of dvbtune here on 2.6, and in the office on 2.4 and the 
driver is behaving as expected.

Can you rebuild with the old config to rule out a tool/app problem? I 
was running tuning tests from 11800 all the way to 127xx using test 
modulators and live streams in the office without a problem. Maybe 
something else for you broke recently?

I know for certain DiSEqC is not supported. I have not done that yet.
