mplayer: failed to open /dev/rtc no such device

I'm trying to play some .wmv files but I keep getting this error:

Failed to open /dev/rtc: No such device (it should be readable by the user.)
I once tried to use makedev or something to create that device but that didn't work out. Maybe I did something wrong. Any pointers would be welcome. What does this device do?

Thanks in advance for the help!

It is a RealTime Clock, that gives mplayer a more accurate timer than what is normally available.
Access to the rtc is not strictly needed for mplayer to work; the reason why your file is not working is something else.

Anyways, to get your rtc working, you have to install rtc module
modprobe rtc
and see that there exists a /dev/rtc node (c,10,135) with user readable permissions.
