I've got a channel that is showing no information in the guide. When this happened in the past, I would report it to Tribune Media Services through a form on Zap2It.com. Zap2It seems to have redesigned (ruined) their site and no longer has any way to report errors in their lineup.
I've submitted the info to TiVo through their form, but have never gotten results from that in the past. Is there any way to report errors to TMS now?
