Directtv uses a modified mpeg 1.5 format. It uses a less robust compression scheme than mpeg 2 and as directtv was pretty much in a hurry to be the first small dish dbs system they went with the mpeg 1.5 scheme while the others that came after used mpeg 2. Of course all directtv programming is encrypted, not sure about Anik F1 but as far as I know your reciever won't handle mpeg 1.5
