My policy was to treat the HD channels as an entirely separate source to the SD 
channels. I therefore have SD tuners which scan 5 transports and the xmltv file 
is edited accordingly. The HD channels are all on a single transport (for now) 
and there are presently only four of them, so the xmltv for these is easy.

By doing it this way the HD tuner cannot get pre-empted by the scheduler wanting 
to record an SD-only program. It is always available for recording HD.

Don't muck about with the channel names, just leave them as they are. If there 
are duplicates of the programming on HD and SD these will show up on mythweb or 
in the front end and you can pick whichever you want.

It may also be a mistake to believe that the HD channels carry *exactly* the 
same programming as the corresponding SD channel. Usually, but not always. In 
addition, the "BBC HD" channel may carry a variety of programs from different 
BBC origins.
