Philips HDR312 TiVo 30-Hour Digital Video Recorder
Beware!!
I have a cable system that has an A-B switch.  Tivo does not support this.   Their solution is to decide between using Tivo on &quot;A&quot; or  &quot;B&quot;.  And when I wanted to switch, it took a 2 hour set up.   Also, if your system requires a cable box you probably wont be able to  watch another channel while Tivo is recording. (you would need another  cable box or cable tuner of some sort)
