[mythtv] AverMedia DVB-T

[mian]

Hi,

I'm trying to get my AverMedia DVB-T card working with Myth, and it does
however the card has composite and s-video analogue inputs aswell as the
digital DVB-T function and because both are used as separate drivers both
cannot be in use at once and it seems just having the DVB-T function of
the card added to Myth makes it so you cannot use the analogue function,
it just reports a load of VIDIOSYNC errors, removing the DVB-T card entry
in Mythsetup let's the composite in function fine.  Is it possible to free
up the DVB-T driver when not in use so it's able to safely switch to the
external inputs and back again?
