I am assuming my posts to the list are working but I don't see them myself
and have had no replies??? can someone confirm please?

Anyway a bit more info...I have gone to 0.26 and I still have the same
problem.

It appears to be something in mythbackend....if I reboot the machine and
use mplayer I get a tuned channel first time. Shutting down mplayer,
starting mythbackend and then watching LiveTV in Mythfrontend then I still
get a failure and a Partial Lock at the first attempt to access each tuner.
