Is this possible without using the locks/creating a custom favorites list by hand? It seems like this is something that should be an option.
Not answering the original question. Locks or Faves...that's it.Chose the HD only option.
We're talking about hiding SD duplicates.One reason not to use locks...
Most HD content (at least for me) is on 129. During a rainstorm I might lose my signal on 129, but still be clear on 119/110. I can change my guide to 'All Channels' and be able to watch the SD version of whatever show I'm watching. If the SD is locked out, you don't get that option.
