.TiVo files in Windows 8

I just started to use Windows 8 and have installed TiVo desktop. In Windows 7 I had no issues to play the .TiVo files in the Windows Media Player. In Windows 8 when I double click on a .TiVo file it does open Windows Media Player, however, there is no video or audio.

I have tried the partial install of TiVo desktop and the full install with no difference.

Any suggestions on how to play native. TiVo files in Windows Media Player in Windows 8 would be appreciated.
