problems with mythtv and pvr-350

changing channel stopped working ages ago (5-6 months). i assumed that it was a bug in myth. now i am wondering.

as far as i can see, mytht pauses the device when changing channel. but somewhere along the way it chokes when unpausing (poll errors).

i notice that hans made some changes in this area back in september. has anyone updated the myth code to support the new ioctls?

running myth master and media_build for the drivers.

any help gratefully received.
