SomeRandomGuy, I hope you're right. Tribune Media Services supplies guide data to ZAP2it and most of the on-line guides. It seems to more accurate than Gemstar.
The MTS guy I asked had to go away for 3 or 4 minutes to find out who the supplier was and came back with a detailed answer. There was an intermediate company in there which I didn't catch but Gemstar was the original source. Maybe he was given info about the old system which I know is Gemstar.
Hopefully, once we get some members with IPTV installed we can get a confirmation.
