Try putting the 64 bit error message into google.
I can't look for you since the error message was mangled in your post.

I am using a MacBook Pro Core 2 Duo and I recently downloaded Handbrake (64 bit) to encode DVD's. I also use the VLC media player. I was trying to rip a DVD and when it brought up the files in handbrake it had an error with the VLC saying it was not 64bit compatible. Do these 2 programs not work well together or is there something else I should try along with the handbrake?
