FIOS IPTV and Tivo compatibility

I received an email about a new FIOS video trail they are running. I just got off the phone with them on getting it setup and am told this is for IPTV. I told them I'm currently using my Tivo Roamio and was told that is fine and it will work.

Is this true? Just my initial search I can't not find much detail other that the one tread "Tivo vs IPTV dilemma" which indicates IPTV is not compatible. So is FIOS IPTV product something different?
