I'm using PDE to convert video's - works dandy - but POSSIBLY after installing the video center, when I go through the file manager to the avi and d-click it, the 800 asks for the app to run it - not being REALLY familiar with Linux, how do I re-associate it?

Also - and I'm pretty sure I know the answer to this, why can't we install (not that I know that is the truth - Evolution as our PIM?
