I think this may be an input group misconfiguration, but you'll need
an HVR-4000 user to give a definitive answer that this works.
The HVR-4000 cannot use DVB-S and DVB-T simultaneously, and this
restriction means that both the DVB-T and DVB-S inputs need to be
configured appropriately to stop MythTV from trying to use them both
at the same time. I don't have this card, but am guessing that
assigning them to the same input group would work.
An additional restriction when using multirec (much more useful on
DVB-T than DVB-S) is that each multirec-enabled card's inputs need to
be assigned to the same input group (this happens automatically if you
choose >1 recordings in capture card setup).
Whether the appropriate 'fix' is to assign *all* of the configured
card inputs on the HVR-4000 to the same input group (allowing the
scheduler or LiveTV session to handle inputs appropriately) is not for
me to say, but I'd give it a go :)
