Windows Share folder control ?

[jill]

 Down to one last issue my Work pc internal drive has come up (Not a MD just my pc windows based) and i do want some folders to show up and be added to the media only issue is its pulling everything aven all the indivisual clips from my camera and some video tutorials i have IE 3400.mpg, 3401.mpg, 3402.mpg makes for a bunch of clutter in the video section how do i edit the items that show up or select the folders mce uses?
want to stop these from showing up but do want my Videos to come up, not shure where to begin.
also the second MD is in my brothers room is it possable to remove some buttons from users screen like the KDE Desktop and Advanced ... pretty much any setting don't want him in there messing up all my hard work
