[mythtv-users] Guide data for vbox and hdhomerun

[myth]

Hi all,

I am starting to add a Vbox http://vboxcomm.com/ to my mythtv setup.
I already have a hdhomerun and use it to receive over-the-air DVB using EIT
as the program data source.

Now I am trying to add the Vbox to the same antenna and ideally this would
share the same program data and be able to use either the Vbox tuners or the
Hdhomerun tuners on an as-needed basis. 

However, it appears that Vbox MUST use a Video Source other than that used
by the Hdhomerun.

Any ideas as to how I can get this configured?

So far, I have setup up an independent Video source for the Vbox and
connected it using Input Connections.
I have scanned the channels for this new Video Source.
I have renamed any channel names and call signs so that the two sources
match for Name, Callsign and Channel number.

By doing a Manual recording, I can force Mythtv to record from the Vbox
source and prove that it records correctly.
However, the Vbox is never selected as a recording option by the scheduler.
When the Hdhomerun tuners are at capacity any additional scheduled recording
just fail.

I'm not sure where to go from here?

Thanks,
Andrew
