Oh! Crash usually means the program exits or the machine locks
up or reboots. The first type is one we'll fix, the latter types
are for the driver writers and kernel developers to fix.

It does this for me. Maybe your timeout is set unreasonably
high? If it is over 20,000 ms the video player will exit
before you see this message on the assumption that the
backend has died.

Well these are not supported in MythTV with the HDHomeRun, they
don't get inserted during the channel scan on the HDHomeRun so
you won't see any tuning problems unless you start hacking the
database or share a source with a different type of tuner.

MythTV does this in SVN head. But these channels don't even get
inserted for the HDHomeRun unless you tell the channel scanner
to insert them. Since the HDHomeRun can't decrypt any channels
it doesn't make much sense to allow these unless there is some
problem at the headend that you are trying to work around.
