Thanks for your suggestions.  I am still waiting to hear from the phantomworks

I don't think there could be outbound RPF failures.  They have an OC3 into us
and no other providers, I had them put in a static default mroute pointing to
our interface and output of the 'sh ip mroute' shows the right RPF neighbor.

No, the logs are clean.

I have asked them for this, but am still waiting to get the results.  They did
turn on  mroute and sa caching.

They still don't show up in my sa-cache.
