The playback of this movie requires a MPEG-1 Layer 3 (MP3) decoder plugin which is not installed.

sudo apt-get install ubuntu-restricted extras

You can also try installing w32codecs or w64 codecs from the medibuntu repository (Which will depend on the architecture of your OS)

Working all through
https://help.ubuntu.com/community/Medibuntu
should help fix almost all your multimedia problems and makes sure you don't miss anything. I would keep using non-free, proprietary components until asked to pay anything, if that ever happens. I guess i have been lucky so far but still hope to go completely OpenSource one day.

I think ActionParsnip has really solved the problem as stated. From his answer i suddenly realised it might be possible to do a bit more.

Good luck and regards from

If VLC or Totem doesn't work, and you want to watch dvd movies or play downloaded flv video files and mp3 files in Ubuntu Linux,
Google for "flv flash Totem internal data stream vlc undf"
... it's better to install everything in 32 bit, even if you have a 64 bit machine, as there are something missing in 64 bit depository like drivers, codecs,...

Play mp3 and dvd under Ubuntu install skype googleearth acroread and other stuffs using Medibuntu

First please install https://help.ubuntu.com/community/RestrictedFormats

You need to have extra repositories enabled..

Please first enable the universe and multiverse repository:

Close and confirm the repository reload.

Then open a Terminal from the menu Applications→Accessories→Terminal

Hi :)

If this is still a problem then please re-post this as a new question
https://answers.launchpad.net/ubuntu/+addquestion
perhaps also at
http://www.linuxquestions.org

Launchpad can only handle most recently asked questions and often the Answers Team races through all the shortest questions first so when you re-post please keep it very brief. You can always copy&paste this link back to this question so that people can see the detail you gave here
https://answers.launchpad.net/ubuntu/+source/totem/+question/81580

When i was answering questions in here it seemed the best answers were
given when the question was posted just as americans were getting back
from work. This was weird because most of the answerers lived in Europe
or Asia at that time lol.

Anyway, good luck and regards from

On my UNR 9.10/karmic, that should be

sudo apt-get install ubuntu-restricted-extras

Note the second dash.

Hi :)

yes when using the command line it is a good idea to use the tab key to "auto-complete" commands/pathnames/names as the linux command-line has a very useful auto-complete feature that works in much the way that mobile phone "predictive texting" should work. I hope this helps

Good luck and regards from
