I am with Mediacom cable and our tivo software is on 21.9.6 v6 I know Mediacom's tivo software is 2-3months behind the Mediacom version. I find that mine is comparable to retail version 21.9.2 v4---when comparing features and glitches (live tv trickplay issues, paused buffer when switching tuners, issues deleting in myshows) I've been talking to Mediacom support. They told me they are in charge of their own tivo software. So I have been telling them about these glitches. But now (after no resolution) they want me to contact tivo support on the tivo website. Anyone know exactly how cable companines distribute tivo software.....does tivo create their software for them or does the cable company? Who to talk to when software glitch complaints don't get resolved?
