Menu building and SEF

[pedroll]

I have strange issues adding links to mainmenu.
if link alias are equal  to category name, the template override doesn't work. (playing with the options of seo joomla/virtuemart suddenly works)
in some category pagination works with parameter in url ?start=8 por second page, and some category ad /results,9-16.html and doesnt work (jump to parent category)

I've unnistalled component and modules and installed again
