hi, I tried mencodeme for linux and it's great!!
I think that with some more options it could become perfct

1) audio encoding
I added
of=mpeg=1
oac=lavc=1
and
lavcopts=acodec=mp2:abitrate=128
and added 128 to vbitrate
and I had a perfectly muxed ksvcd
I think it would be easy to implemet
2) a button to save the final complete script with a name
so I can create the scripts with the gui and then execute them when i want maybe on another machine that doesn't have X installed...
what do you think about that?
ps. sorry for my english
