I won't be the one to blame anyone else but...
are these KVCD image files of your friend the same as here

Yes, sure they aren't, since if that thread was closed, you wouldn't try to make again a question on the same topic, would you?.
I just ask since your question is quite similar to that, and you got your friend's images in just 2 hours and a half...
Sure your friend still keeps the original videos, and you can ask him them to try to make your own KVCD, and see by yourself the powerful encoding methods we use here...
