First of all, you need to use a few more options for mencoder.  This works for me, but if you want to author a DVD, I can't offer any help past this mail.  Your best bet for this would be to use tmpgenc, as that's one of the things it was written for.  Best case scenario, you *might* be able to get an (S)VCD out of this, IF you use the correct specs (dimensions, bitrate, etc).  See TOOLS/mencvcd for an example script.

cat *.mpg >output.mpg
mencoder output.mpg -of mpeg -ovc lavc -lavcopts vcodec=mpeg1video -oac copy -o newoutput.mpg

Good luck!
