Yesterday I wrote about the EPG issues affecting ATSC users which was causing some headaches. Today Microsoft have updated the thread on TGB to say they have a fix.

Hi all,
As reported, some Windows Media Center users experienced guide data missing for certain channels in the Windows Media Center Guide in Windows Vista. The channels were for a limited number of analog transmissions that were recently shut-off by local broadcasters. We are currently rolling out a solution, and expect the problem to be resolved by end-of-day today.
Some of you may already find that the data is now available. If it hasn’t been updated automatically, you can also try a manual guide download. You can do this by going to Tasks –> Settings –> TV –> Guide –> Get Latest Guide Listings
To quench the technical minds that will inevitably ask me what the cause was:
In versions of Windows Media Center pre TV Pack, the ATSC channels were mapped to the Analog counterpart of the Antenna channels for their data. Since some of these channels were recently switched off by local broadcasters, our provider removed them from the Antenna lineups. We were able to go to our provider and have these channels added back in, thus the mappings are valid again.
Going forward, we are working on a long-term solution to prevent future disruption of this data.
If you have any specific questions about this issue, feel free to drop me a PM. I will try to post back here once I can confirm that this is expected to be resolved for everyone.
Microsoft sincerely apologizes to those who were inconvenienced.

It’s great to see Microsoft respond quickly and get a fix to the issue
