While I understand, was it really ever listed as working with DirecTV2PC?
When you pay $400 for a receiver, you do want everything to work. That includes the so-call FREE stuff.
Was this the reason you bought this brand new receiver?
It seems one thing to "buy" something and have it not work, while being another that it doesn't have all the options you expected.
The HR20s came with an OTA tuner, but it was six months before the software activated it. This to me rises to the level of "deserving" credits, while not having a "FREE app" work doesn't, but YMMV.
