It's a tricky one.   I've struggled with this one too.   I don't know 
whether my approach is any good, but here's what I do.

    * Define both sets of channels in mythtv
    * Set a recording priority to a negative value on the HD channels. 
      Because the majority of shows aren't shown in HD, they are just
      scaled up to HD res.  So if I say record show X, it will have a
      priority to record on the SD channel.
    * If I really want to record a HD program, say CSI.  I can setup a
      recording rule that forces it to record the HD.
