TV Guide not fully populating

[jasonwilliams 36]

Hello,

I have noticed recently that my guide is not populating for some channels.  When I look at the guide from my provider directly from the cable box, they are populated.  I have noticed that the digital option does not appear when I try to lookup different providers in my area, so I tried the options that were there.  

Is there some way to look at the source to see if the channels are missing there too?

HI, did you check the channel mappings in live tv setup to ensure that each tuner channel is mapped to a guide channel?

I'm an idiot!  Thanks.  They weren't mapped.
