hmmm...
first off, you should UNCHECK auto-add. if you use commands, you really don't need it

after that, your commands look right.
your regions look right. clones are 640x360 which is 50% of your screen.. so the aspect ratio should be correct

when you say it doesn't look right, what do you mean? just enlarged or stretched and out of proportions?

(got a screen shot by chance?)
