Package dependencies cannot be resolved

I am using Ubuntu 12.04. When I try to open a video file like a file with an .mkv extension with mplayer it says it requires some multimedia plugins like gstreamer.

When I tried to install the required multimedia plugins in the Ubuntu Software Center this error message appeared.

This error could be caused by required additional software packages
which are missing or not installable. Furthermore there could be a
conflict between software packages which are not allowed to be
installed at the same time.

When I tried to install the required multimedia plugins in the terminal this error message appeared.

 The following packages have unmet dependencies:

I searched and found that the most solution said:

sudo apt-get clean

sudo apt-get autoclean

sudo apt-get install -f

and I tried them and nothing happened.

My /etc/apt/sources.list :

Looking at your error messages, I guess you either installed packages which are newer version than the standard repo (I might not the case) or installed packages which depends on the older versions of packages (Most probably) and it is not updated for the latest dependencies (thus requiring older versions).

I suggest you to do these: (most of the cases, it works)

Install aptitude with sudo apt-get install aptitude command

Try to install the package you are willing to install with command like
```
sudo aptitude install <package-name>
```

Aptitude will show you the error and present you a possible (best) solution. You will be asked to choose from 3 options with a message like
```
Accept this solution? [Y/n/q/?]
```
If you see that your desired package is not listed in the (will be) installed list, simply press n to let aptitude give you the next best solution. After several trial, (if you are lucky) you will see that your desired packages are in installable list and the packages causing the dependency problems will be showing in downgrade list. In this stage Press Y to accept the solution. The packages will be downgraded to satisfy to installation request.

I'm sorry that, I can't give you a demo run of aptitude like this, but you can check this page to see some of it's action.
