Playback of audio and video

Here in India, we like to use the Ubuntu very much...
But, due to the lack of sufficient basic plugins such as the ability to play mp3 or any video file, even though it has a player, we dont use the software and turn to windows instead....
the videos can only be played if we have an internet connection and after downloading files from the internet...
But what if we dont have internet connected to our homes???
even installation packages are not available for download.....

it has to be connected to the internet and has to download the packages by itself... which is not a feature which we desire where internet connectivity is not available.....

what i would say is that, instead of including more than two players in the iso file, that can be replaced by a single player that plays all the common formats if disk space becomes an issue....
or else, upgrade the installation cd to an installation dvd where more space can be found and more applications and support for different formats can be included....
