After installing Mavericks my dvd player quit working

Resetting smc surely didn't work for me, back in the day...😐

Glad it worked for you, though! 🙂

Was running latest Mavericks when performing "my hack", now running latest Yosemite. All is dandy.

BTW I only put the file in HD>library>preferences, not under usr.

Many thanks Bpiper55,

I alms gave up, I tired everything but with no success ... now I followed your steps and it worked ... hope it lasts!

Cheers,
