Awesome work - finally can make a Mp4 file with multiple audio , subs and chapters.
Small snag here , force frame rate option shows but will not allow selection ( check box will not tick and open frame rate value for changing to needed setting )
(Edit) other issue , on my PC i have to select show commandline just to get the GUI to show itself below the output file box ( I cannot see options / mux line ) Once thats selected I can see all the GUI fine but the command line still will not show unless I enable program to run in fullscreen , WinXP Corp - 1600x1200 res Ty
