Well I made the change but it broke things.  Meaining all playback was just
a black screen.  So I guess that won't work.

I'm going to try and update the Driver to the 180.29 version and then play
with the configs some more.   Hopefully I'll get lucky.  I did have this
working before.   Not sure what I messed up.

Thanks
