DVD Player doesn't start anymore - ??10

[Booomy]

Hi,

my DVD Player doesn't start anymore. Along with some other applications(iChat, iCal, Expose, Automator) it all of a sudden is only displayed with the default application icon - the thing with the ruler and the brush and stuff.
The other applications seem to work fine except of the wrong icon thing.

When I try to start my DVD Player a popup comes up that says in bold letters ?? and underneath that ??10.

Does anybody know anything about this problem?

Thanks in advance

Hey try this-go to hd>users>library>preferences and find the cd/dvd preferences>trash them and dump them. Try again.
Maybe it will work. ALSO YOU CAN TRASH APPLE.COM.SYSTEMPREFERENCES.
