I think you need to manually add it in media center first.GIJOE4LIFE wrote:Once into guide tool I could change the most important channels that had the wrong data, but it would not let me add the cable channels that were not listed on the left side. For example channel 512 is one of the hbo's, the rovi guide does not have it on the left side of the guide tool, it won't let me add channel 512. If the channel number is not listed on the left pane of the guide tool, it will not let me add that channel number.
From MikeDupp in another thread:
Manually add all your missing channels in WMC. Close WMC.
Start Guide Tool, click OK on the localhost dialog. Let WMC start. Minimize WMC.
Go back to Guide Tool and subscribe the newly added channels to new lineups. It's ok to mix and match lineups.
After you subscribe all of your manually added channels,close Guide Tool and maximize WMC again. Get latest Guide listings. Wait for notification that download is complete.
Close WMC, then restart it. Guide data should now be current.
