Almost did it. But if there was something after and in the same line of
the "comment" I want commented it wouldnt be taken.
from :
    comment xxx
to :
/*    comment*/ xxx
and I wanted :
/*    comment xxx*/

But it helped a lot, I finally got :
>>> MyPattern =
re.compile(r'(.*?Start.*?)((^.*?comment.*?)*)(^.*?comment.*?$)(.*?end)',
re.S | re.M )

which did the trick.
Thanks a lot Marco!
