afaik, HD shows are flagged by the listings source. if mythtv sees the 'also
in HD' tag, and you have HD as +1 priority over the SD recording, then it
will record in HD.
if priority is equal, then it will record the most convienent show.... be it
next showing, or when a tuner becomes free if all tuners are in use.

i've set my 0.24.1 box up with HD priority of +2. this way i can still +1 to
a specific show, but have HD recordings still take priority.

Jim, in the case of UK listings, there can be a difference in SD/HD content.
for example in the UK, channel4 have identical SD and HD channel broadcast.
however, some of the older simpsons episodes will display in 4:3 ratio on
the HD channel. channel4 dont seem to scale the image, so the SD channel
would be favourable.
