Cannot use menu after burning DVD with NV3

After I burn a DVD (with chapters or not), I cannot use the arrow buttons on my remote to move the “highlight” in my menu to select anything. the only way that I can play a video / chapter is by using the # buttons. If anyone has any ideas, help would be greatly appreciated.

thanks

I am using a P4 3 ghz, 1gb ram, and a brand new plextor 750A burner.

The previous burned that I was using is broken, but when it worked I did not have this problem.

Thanks again.
