Same serial protocol, eh?  I've been wondering, since the and files I've found seem to be pretty much identical.  I have a
fairly old Sony (5 yrs?) that has worked fine with  the that I
found.  I'm planning on expanding my backend to two PVR250's, and I'll
need an additional DirecTV recieiver, but the only plain-and-simple
receiver I can find is non-branded (or DirecTV-branded).  I've been
wondering if the serial protocol on this device will be the same as
the Sony and RCA models.  Anybody know?
