I had the same problem a while ago when updating to some new nvidia drivers and figured it out. I can't find the post, so I'll just show you how to fix it
The problem is caused by the "PlayOnMy" shell extension that nvidia drivers add to your registry for Avi, Mpeg, and WMV files. This adds the 'Play on my Tv' option to the list when you right-click these media files.
There's no easy way to remove them without running regedit (that I know of), and you will have to do this every time you re-install nvidia drivers.
So, here's what to do:
1. Run Regedit
2. Press f3 and search for "PlayOnMyTV"
3. Erase all instances of "PlayOnMyTV" -
I saw them specifically in: HKEY_CLASSES_ROOT\AVIFile\shellex\ContextMenuHandlers\PlayOnMyTV
Erase only te "PlayOnMyTV" folder/key/whatever it's called. You will have one of these for each movie type.
