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.

I wonder if we can be smarter/faster about the xc5000 firmware uploads?
..

The firmware downloads take a little over six seconds, each time,
and appear to be done after any "sleep" of the device.

The "un-ticked checkbox" above means that the device will NEVER
be put to sleep, though..


One problem (not new) remains:  the device remains "live" on the USB
even when the system is powered-off.  It stays quite warm to the touch
and is obviously wasting power this way.

Is there not something the driver could do to put it to sleep
on system shutdown, so that it draws much less power, per USB spec ?

thanks!
