help needed in converting

hi
I was wondering if this is possible on some "easy way"
I extracted from Frozen Throne last fight Arthas vs Illidan
abd I have it in both MDL and MDX format

unfortunately war3 viewer crashes when I try open it
and I'd like to have that whole cinematics actually converted into Video... (avi/mp4/whatever)

Have you tried recording it off your screen with fraps (or something similar)?

too weak pc to do it
thats why I asked direct convert :)

Find it on youtube and DL from there? (google youtube downloaders)
