Right now I've got some inexpensive RCA receiver (one of the $49 Wal-Mart specials from awhile ago) hooked to a standalone TiVo. (I had a Hughes receiver, but got the RCA for the serial connection between it and the SA TiVo.) Anyone with strong opinions on the various D* HDTV receivers out on the market? I'd like something with the serial port so I could continue to use the SA TiVo to control it to record SD channels. Thanks!
