Thanks Mielr, I'll ckeck it for sure.
My only grip about such threads is that it is for the technical "elite" only. A lot of the "preservation" forum threads are more apparented to the "technical discussions" sections 'imho', and if it's yet quite difficult to follow such discussion for someone who is a stranger to tech ways, imagine for the non-english that I am.
Well, I guess one have to accept this particularity and give the effort it requires to find out by himself ... :)
