Converting from CVSNT

[Giampaolo Fadel]

Hello,
I have some CVSNT repository that I want to convert to HG. (The server 
and the client are Windows XP).
I used the convert extension and all work fine except two points:
1) The branches that in CVS are closed (merged to the main trunk), after 
the import, they are not closed and they generated new heads.
This point is not important for me, my repositories are enough simple 
and I can manually rearrange the history.
2) All line of text files end with LF and not with CR LF.
This point is more important because the source files after the import 
are, de facto, different.

Any idea, suggestion,

Mercurial is 1.2.1 and CVSNT is 2.5.03.2382

I've tried with a conversion CVS to SVN and then from SVN to HG, but, 
concerning the CR LF, the result is the same. While the history is 
completely different, after the conversion I have about twenty unclosed 
branch (the original repository has only two branch) with name "unlabelled".

I've tried even doing the direct conversion in a Linux machine and the 
CR LF problem persists.

Thanks
