Having checked my epg getting script, it uses a little python script from
Hads (myth_recorder_status) that checks that a cardid is free. Is this
still going to work with virtual tuners?

My DVB card appears as tuners 7, 8 & 9 and when its busy with a single
recording it uses cardid 9 - I can see problems with testing just for this
though when 2 recording start close to each other, presumably on virtual
tuners 8 & 9 in my case, and if the one on tuner 9 finishes then my script
will check and assume the DVB card is free and start playing with it :-(

Not knowing much about python, is it possible to pass a list of cardids to
myth_recorder_status and check they are all free?
