SD: NBA LP works fine.. HD: 727 Error

[yourbeliefs]

I'm trying to watch my Bulls stop their streak of sucking against the Denver Nuggets on NBA7 / Ch 757, and while on the guide it has the SD and HD games listed, when I try to watch the HD version, I get the 727 Error...

PLEASE advise...

EDIT: Ok... why do I not get this in HD when I get both RSN's with HD feeds that could possibly be carrying this game??
