Install and Config MPlayer on Ubuntu

I tried to install realplayer on Ubuntu 7.0.4, no luck, even if I fixed the RealPlayer and SCIM conflict. Suggested by Yi, I decided to install MPlayer.

Follow the instruction on: http://ubuntuguide.org/wiki/Ubuntu:Feisty#How_to_install_MPlayer_Multimedia_Player, to install MPlayer.

There was some extra steps to get MPlayer to play a rmvb file on my Vostro 200 box with Intel GMA 3100(G33) graphics card and DELL E207WFP wide screen LCD.

Error code: error opening/initializing the selected video_out (-vo)device
Solution: Open a mplayer, select configure (right click mouse --> Preferences) select Video section and after select xv or x11

Error code: cannot find the codec matching -vo and video format 0x30345652
Solution: install codec available in aptitude using the command:

sudo aptitude install gstreamer0.10-pitfdll gstreamer0.10-ffmpeg gstreamer0.10-gl gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse gstreamer0.10-plugins-ugly gstreamer0.10-plugins-ugly-multiverse libxine-extracodecs w32codecs

Error: The video does not zoom correctly
Solution: sudo gedit /etc/mplayer/mpalyer.conf
and uncomment the following setup:
monitoraspect=16:9
zoom=true

Now I could play the rmvb video files without any problems. Next time, I'll get audio fine tuned.
