Links to Media Files

I am a newbie to all this. I have the black Apple TV and have purchased the aTV Flash for it, but before I go ahead and jailbreak & do the ‘install’ can someone clarify for me if I do do this, will I lose the current links that have been set up to the media files on my home computer. Or even will I lose just lose all the current settings if I even jailbreak it.

Help please!
