Missing Channels in Live TV Guide

[MSquid]

I've noticed that two channels are missing in my Live TV Guide. In my area (zip 08402) the channel numbers are 300 (HBOHD) and 301 (HBO). As far as I've noticed, all the other channels are listed. In Channel Setup I've asked for all channels to be listed, and if I scroll down to channels 300 and 301, they are listed with green dots as enabled. But they do not appear in my live listings.

I've tried opening and closing Sage. Unenabling and then re-enabling the channels, and they still don't appear.

Is it just me? Am I missing something easy? Does anyone else have a similar problem? If I use my browser to check the Zap2It listings for my area, the channels are listed, but not in my Sage.

Thanks!
Joe
