[mythtv] QAM tuning problem with HD-3000 & kernel DVB drivers

[Bruce Pennypacker]

Hi all,

I've been unable to tune QAM channels on my HD-3000 with mythtv despite 
being able to extract it using the azap, dtvscan, etc. tools.  In 
searching around I've come across many similar reports of problems with 
this combination.   I've tried both the 0.18.1 release and the CVS tree 
from yesterday with the same results - doing a channel scan simply 
results in all of the channels resulting in "Timeout Scanning Channel" 
when it's able to lock onto a channel.

I was wondering if anybody knows about this problem and/or may be 
working on it.  It's been years since I've done any serious c/c++ 
development/debugging and I know next to nothing about DTV, QAM, etc. 
but I was thinking of firing up gdb to see if I could figure out why 
this may be happening.  Of course I don't want to expend the effort if 
somebody else is already looking into it, hence my query here before I 
take the plunge.
