Which national HD channels are simulcasts/mirrors

[othy]

Is there a source out there that shows which national HD channels are mirrors or simulcasts of their SD cousins? For example, Discovery HD seems to show the same programming as Discovery.

With my new HD-PVR, I'd like to remap as many channels as possible so that they show once on the Guide and tuner merit determines whether I get HD or SD. I hate to just glance at the current listings to see if they match...

At least on DirecTV, all the HD channels appear to be mirrors of their SD counterparts. I believe they would change the name if it was showing something different (ie. ESPN2, ESPNCL, etc)

Thanks for the reply. I thought so, and I'm going to set it up that way for now.

If anyone knows of any notable exceptions, let me know.
