Open Notepad as Administrator & edit the hosts file found @ \Windows\system32\drivers\etc. "All Files"
copy the below 2 lines and paste them in this file below the entries that exist in it.
65.55.186.113 data.tvdownload.microsoft.com
72.246.56.59 cdn.epg.tvdownload.microsoft.com
Closed WMC
Open task scheduler. Run both MediaCenterRecoverTask and the ObjectStoreRecoverTask.
Uninstalled WMC from programs and features.
Reboot.
Open Windows Explorer and C:\ProgramData\microsoft\ehome
Delete all mcepg3-x folders and files.
Opened regedit32 and drill down to
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Service\Epg]
Deleted all the keys underneath "the default key probably won't delete" don't worry, that's normal.
Do the same for
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Settings\ProgramGuide]
Now reinstall WMC from program and feature and reboot.
It will probably give a "Serious error message when you start it" That is a good thing... probably...
Open WMC and run the setup. It should now download the listing for you with out error.
Let me know if this fixes it for you.

Well I tried it but it did not work for me. I then did what The Mac Post#1780 Suggested and backed up one step and just keep running tuner setup until it went through the setup. Only it was not necessary to do the Ipconfig/flushdns. ( i have done it both ways) This is the only procedure that has let me get past the TV data download failure. But still no guide.
I went to schedule updates and tried updating the guide many times, but that did not work.
It still does not have the line "about guide" in the Guide section, so I guess it has not switched to Rovi?
I am surviving by recording OTA with NextPVR and it is working fairly well, but for some reason the Fast Forward does not work very well. Have it set to intercept commands from my MC remote?
