This looks like a quirk with CFL programming. Tribune Media Services (which also runs Zap2it.com) provides the guide info for Mediaroom. If you go to Zap2it.com and search for CFL Football, you'll see the following:
- CFL Football (TV Show)
- CFL Football (Calgary Stampeders at Winnipeg Blue Bombers: Fri, Nov 5, 7:00 PM)
- CFL Football (BC Lions at Hamilton Tiger-Cats: Sat, Nov 6, 1:00 PM)
- CFL Football (Edmonton Eskimos at Saskatchewan Roughriders: Sat, Nov 6, 6:00 PM)
- CFL Football (Toronto Argonauts at Montreal Alouettes: Sun, Nov 7, 3:00 PM)
If you click on the generic "CFL Football (TV Show)", you'll see:
- Eastern Conference Semifinal: Toronto Argonauts at Hamilton Tiger-Cats
- Western Conference Semifinal: TBA at Saskatchewan Roughriders
This looks like either the semifinals are being assigned a different series-id or maybe the series-id will be assigned once the teams are finalized.
I set up a series recording for one of the games on Nov. 14 and it marked only the 2 games on the 14th, indicating they are treated as the same series-id, but different than the series-id of the regular season games. I'm not sure if the series-id will be changed prior to the games being played.
After that long-winded explanation, this looks like a potential guide error, not a bug in the software.
