You cannot change anything with -ovc copy.

Wait. You tell it to framecopy (don't reencode) and then you expect it
to reencode? Make up your mind. If you do reencode, you'll reduce
quality or increase filesize. I don't see why you want to do this at
all. It's the same as people who reencode their 64kbps mp3s to 320kbit
to "get back the quality"...

Use -of mpeg to make an mpeg file, but it's experimental and probably
won't work. MEncoder is for making avi files.

These are not supported for various reasons, but oh well.
