Unfortunately, I've had issues coming using the cvs2svn route, too.
It seems better than the current state of hg convert from cvs, but it
still gives me files on branches that should not be there after
converting to hg.

I'll try to produce a simple example if I can.

In any case, it may be that the hgext/convert/cvs*.py could
learn something from cvs2svn.
