MTS.ca is down right now so I can't post the link, but I found it yesterday in the section on apps. look for App for TV in Ultimate TV and then Miso.
Were you able to "pair" Miso on your smartphone with MTS TV? It seems like you're supposed to be able to do that, but I can't figure out how (at least on my iPhone).
What's New in Version 3.2.4
- Connect Miso with your internet-enabled MTS Ultimate TV receiver to automatically identify what's on TV and synchronize SideShows.
