I guess the D* boxes are really bad.... When I had TW, the 8300 used software from Pioneer (the same Pioneer that makes audio equipment) and it was reasonably good. It was limited, but worked okay. Later, TW developed their own in-house software that in most opinions, "sucks".
What interface/software does Blue Ridge use on them, if you know ?
Passport on non DVR's, Passport Echo on DVR's.
Yes, it was Pioneer, then Aptiv, now Rovi (but not branded as such yet).
