This may not be an exact answer to your problem, but might point you into the right direction:

At first, you can't access /dev/rtc because you don't have the access rights for that. The quick and dirty solution to that is to chmod the device to 666. The correct solution is to create a special group. The group should have access to that device. Add yourself to that group.

The chmod 666 is fine for testing.

The next thing which goes wrong is that you do 'su'.

Once you are 'su', you can't open a window (display) in X anymore. That is the second error message.

You can workaround this to Alt-F2 to start the app. Then you as user opens the display, but the app is run with 'su' credentials. That should overcome any access errors to devices. Once it runs here, you know what to look for.

you can also download sux which is a smart su and lets you run x apps from console as super user. Cheers

DONT DO THIS, it is a very bad idea to just start working with superuser privileges. The right way to solve your problem is, as stated above, to make a group that can rw to /dev/rtc.

$ su
$ groupadd rtc
$ chmod g+rw /dev/rtc

You should check out the man page for usermod, but I think this does the trick:
$ usermod -g `groups <username>` rtc <username>

then log off, log in and mplayer will work...
