Windows Media Center recently switched its source for EPG(Electronic Program Guide) from Zap2it to Rovi and it’s resulted in “No data available” in the guide for some. Microsoft confirmed the issue and have said they’re working on it. It seems like there’s some issues with certain zip codes and providers when it comes to Rovi. I had success switching to a different provider for my zip code using 1geek1tool.com’s guide tool which you can download here; zip codes can be found using zipmap.net.
Of course there’s other suggestions to try to fix the EPG issue over at TheGreenButton forums. Anyone else having this issue?
