I've tried the Fancast plug in app, but it did not play at all. Python error, so I uninstalled it.
I tried using the Fancast RSS feeds for specific shows in my Boxee web account a few weeks ago, but they did not work either.
Today, I tried a few and they are now working...mostly. I had some play just fine. Wow, cool. Some will play for a minute or two but then stop with a pop up stating: your pc is struggling to play the video. Please choose "optimize". Of course you can't choose anything, so you have to stop the video.
I was able to get 75% of my choices to play full term. Check it out. Maybe what you like will play normally.
Example: Diner, Drive-ins and Dives
