[mythtv] 0.19 LiveTV frontend display freeze

[Robin Gilks]

Greetings

Fresh install of the all new shiny 0.19 (updated from svn r8916) and I'm
STILL getting a display freeze on a program guide transition.

Combined backend/frontend on a DISKLESS Via SP13000 using all nfs mounts
over 100M ethernet to a jfs virtual partition on an LVM2 filestore over
raid5.

Come change of program, the backend switches to a new file but the
frontend doesn't follow it - its left with a still frame of the end of the
program just finished. The frontend is alive as I can ESC out and re-enter
LiveTV again.

Looks like a timing issue with remote storage as its totally reproducable,
interesting that a frontend on the fileserver machine suffers exactly the
same freeze frame problem :-(

Assistance required on what logging to enable so this can be tracked down.

Cheers...
