But surely the point of calling poll() on the front end's descriptor is either 
to be notified once the tuning algorithm has locked, or to be told that LOCK has 
failed? This would certainly seem to have been xine's assumption for the past 
10+ years.

I don't have a git tree to bisect with, so I expect I'll have to resort to more 
"old fashioned" methods.

Me too, because this bug is affecting *every* DVB adapter that I own. (All USB, 
but anyway...)

Cheers,
