Sign up required to view videos

How do I make it to where users are required to sign up before viewing the videos. I understand we can set the Guest Limit in the admin to a low number like 10 or 0 but what it does is it allows anybody to view a video then ask them to sign up after. Any suggestions?

TIA

templates > view_video.tpl

Find :
{$VSHARE_PLAYER}

Replace with:

{if $smarty.session.UID ne ""}{$VSHARE_PLAYER}{else} SIGNUP NOW YOU FREELOADER :p{/if}
