 Hello all,

 I am having terrible troubles getting DVB channels to tune in the latest
 SVN (8917).
 Mostly the trouble is with HD channels, in which case I never get to see
 any video,
 mythfrontend totally locks up with a black screen, but the backend
 continues to record.

 In fact, it has been the case twice now where the backend has continued to
 record *after* the frontend had been forceably killed causing endless
 recording resulting in 80GB of mpg files that never seem to get expired by
 the backend - I've had a total 100% partition fill a couple times now.

 I hope this not a duplicate of an existing ticket, but I don't think that
 there is
 currently anything open about this (forgive me if I missed it).

 Anyway, I've done all the related informating gathering and attached to
 this ticket
 you will find the frontend and backend gdb.txt from the point at which the
 frontend stops responding (I entered LiveTV, an SD channel tuned, then I
 tried to change to another SD (yes, SD, not HD)), the frontend log and the
 backend log ("-v record").

 Here's the contents of my gdbcommands for the frontend (backend was the
    handle SIGPIPE nostop noprint
    handle SIG33 nostop noprint
    set logging on
    set pagination off
    set args -l mythfrontend-debugging.log -v record,channel,siparser
    thread apply all bt full
    set logging off
