Option 1 - Use SSM for the HD content. So an RP isn't required.
Option 2 - make a local router the RP for the HD Specific Groups. Override
the auto-rp configuration. Put up a multicast boundary so that these groups
don't see the light of day on the wan interface.
From your message I can't tell if everything has to remain local to you, and
the RP not being local is what is causing the issues or not.
