My system is 64-bit Ubuntu 12.04 using a Nvidia GeForce GTX 285M Graphics with 1GB GDDR3 Video Memory.
Since upgrading to Ubuntu 12.04, I can no longer see youtube videos in Firefox, Totem or Minitube.
I've included screenshots of what I see in Firefox.
When I right-click on the Firefox section of where the video should display, I see the following options: Copy, Open with "Movie Player", Fullscreen. When I choose Open with Movie Player, Totem opens and displays an error message which says: An Error occured. Location not found. Ive included a screenshot of the Totem error message as well.
Any suggestions on how I can determine why I can no longer see youtube videos?
