There is definitely a regression, in that it doesn't work without
config changes to Myth.  This is due to the new way that firmware uploads
are implemented in xc5000:  slower, and more often than before.

But the MythTV workaround required is simple:

3. In mythtv-setup -> CaptureCards -> DVB:1 -> RecordingOptions
there is a tickbox for "Open DVB Card on Demand".  It was ticked,
so I un-ticked that box.  Everything now works!

When that tickbox was selected, the xc5000 took five (5) seconds to "open",
as it did the firmware upload every time.  This appeared to exceed some
timeout inside myth.

With the tickbox NOT ticked, myth just opens the tuner once at startup,
and keeps it open, so no more delay when it wants to use it.


Dunno what to say about this one.

Cheers
