MEncoder can create MPEG (MPEG-PS) format output files. Usually, when you are using MPEG-1 or MPEG-2 video, it is because you are encoding for a constrained format such as SVCD, VCD, or DVD.

To change MEncoder's output file format, use the -of mpeg option.

Creating an MPEG-1 file suitable to be played on systems with minimal multimedia support, such as default Windows installs:

mencoder input.avi -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 \

-o output.mpg -oac lavc -lavcopts acodec=mp2:abitrate=224 -ovc lavc \

-lavcopts vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3

This command gives you the charset of a text file, which would be handy if you have no idea of the encoding.

Useful if non-ascii characters in filenames have been improperly encoded. Replace "PROBLEM" with the incorrect characters (e.g. 'é'), and "FIX" with the correct ones (e.g. '?').
