first of all, thanks to Dan. The last modifications in MLT will help a lot
and I'm waiting for kdenlive to incorporate and take advantage of them !!!
I think I've found the problem with the script (hopefully !!). I'm going to
update it in the forum, so appreciate if somebody can test and comment.
BDW, I think it should be better if we continue this discussion in the
forum. Do not think this is something to be with kdenlive development ;-)
