[MPlayer-users] How to convert .VOB to .mpg (MPEG1)

[James Courtier-Dutton]

Hi,

I am trying to convert a .VOB file from MPEG2 to MPEG1.
I run into the following error messages (full output below)
[mpeg1video @ 009E24E8]MPEG1/2 does not support 2997/100 fps

Is there something I can add to the command line to fix this?

James
