[MPlayer-users] mencoding DVD with multiple display rates

[Steven M. Schultz]

Hi!

	I've a DVD that's proving troublesome to transcode using mencoder and
	was wondering if someone has a spare clue or two what -vf settings 
	should be  used.

	With mplayer dvd://1 I see the frame rate switch several times
	during the first 30 seconds or so (splashscreen/intro) before 
	settling down to film (23.976):

Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.

	Maintaining A/V sync thru the bouncing frame rates is challenging
	so far.

	"The Abominable Dr. Phibes" (starring Vincent Price) in case
	anyone's interested or has the DVD.   

	Cheers,
