To concatenate mpeg videos use
copy /b "movie1.mpg" + "movie2.mpg" movie_cat.mpg
in windows or
cat movie1.mpg movie2.mpg > movie_cat.mpg
in linux. Then use ffmpeg or winff to convert the concatenated file again to get all the header information right.
To add a commonly used video conversion to the right-click on windows open regedit and add a new key called Convert (or whatever you want the option in the right-click menu to be called) to the shell folder of the source file type in HKEY_LOCAL_MACHINE\SOFTWARE\Classes, for example VLC.mod. Then to that add a key called command and give it a value like "C:\Program Files\WinFF\convert.bat" "%1". In the bat file you can have your ffmpeg conversion like ffmpeg.exe -a %1 <options> %1.mpg to conver filename.mod to filename.mod.mpg. You can get option ideas from WinFF by looking at Edit - Presets.
