I have a Sony SAT-50 being run by my Sony Series 2 SA TIVO using a serial control cable which was originally supplied with my Sony series 1 SA TIVO. It works great. The problem is that newer Sony receivers and, from what I can see, all the other newer receivers don't have a serial connector. Most, but not all, have a low speed data port which, in theory, can be controlled by TIVO using a Home Control Cable which can be purchased from TIVO for a nominal amount. The Home Control Cable is a stero plug which fits into the TIVO with an RJ14 plug which fits the low speed data port. I purchased a Hughes GAEBOA specifically because it had a low speed data port and was very reasonably priced (under $100). I couldn't get it to work using the Home Control Cable and found on this bulletinboard a post saying the low speed data port wasn't programmed to do anything! I then e-mailed Sony and was told that none of its receivers could be controlled by a TIVO other than using IR. I hope this clarification helps. If anyone knows how to connect so that TIVO controls the receiver other than by IR, I sure would like to know.
