1) Don't use the script from Clip-Share.com . I use it on Video Slacker.com and it really lacks a lot of features. Support is weak, also! For changing the layout, you have a couple hundred pages worth of templates to change. NO CSS FOR THIS!!
2) Don't use the Alstrasoft script, either. I used their scripts on several sites and they are always BUGGY AS HELL! Google search alstrasoft and see what you get.
If you are looking for a great script with support, go to this site and your worries are over! They don't even charge for updates!

A bunch of us who were using the clip-share.com script have either moved or moving to this one.
