Ubuntu 12.04 contains Rhythmbox and a video player. These tend to give me an error when I try to play, say, an .mp3 file.
Required plugin not found: Python (v2.7) requires to install plugins to play media files of the following type: MPEG-1 Layer 3 (MP3) decoder
Apparently, this is one way of solving the problem, but it seems a little long winded. Is it better to just install a new (and "complete") copy of Rhythmbox? I know that other OSs like Zorin has no issues with playing media files.
(Alternatively, VLC player might be better but I don't have a good internet connection on my Linux computer at the moment.)
