I just installed 12.04 LTS in my machine, and when I use movie player, it only plays the sound and shows no video.
The file I've been trying to play is mp4. I installed ffmpeg from the terminal if it has anything to do with the problem.
Hope someone can help me, once I liked Ubuntu. I had OpenSuse11.4 KDE installed before and it played videos without problems.
