Negative Positive
Title: Beware!!
Review: 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 "A" or "B". 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)
Is the review positive or negative?
