VLC Media Player
I have been fighting with the viewing of versions video formats. Luckily I could open two different video formats with this player, which could not be opened with Quicktime. So I will keep this on my list, just in case. Pity that there are no plugins for iTunes. I hate using multiple players, I want just one solution for all my media.

This is a new application taht allows users to create fairly complicated websites. I participated in the beta period and was able to recreate one of my websites. In fact I was very happy. There were some bugs present, but they were pretty quickly resolved. So now that I redesigned this website, I will continue to use it. I might even start playing with designs and other website. And I would like to see a way to integrate it with Expression Engine in some way.
