free m2v+mp2 multiplex (other than ImagoMPEG)?

[tff]

hi
i have dozens of (xx.m2v , xx.mp2) files from .ts videos that i demuxed using ProjectX.
now i want to reverse that , i want them back each set to 1 .mpg or .ts file.
ImagoMPEG-Muxer is good and is free , is there another free tool to multiplex m2v+mp2 ?
the reason is ImagoMPEG sometimes fails to do its job (error message in processing with a result of 1 .mpg file with no audio in the second half of the film.)

Try tsmuxer!

or ffmpeg,

ffmpeg -i video.m2v -i audio.mp2 -vcodec copy -acodec copy video.ts

+ Muxman + Cuttermaran through Mplex but it preserves end time code for each video file, and if it is not corrected it may cause a slight pause on some players.

This is the command line that DVDAuthorGUI uses to mux with ffmpeg:
ffmpeg.exe -fflags genpts -i title.m2v -i title.mp2 -vcodec copy -acodec copy -target ntsc-dvd title1.mpg

and mplex:
mplex.exe -f 8 -o title1.mpg title1.m2v title1.ac3

Both are command line utilities.
