You've just earned Brownie Points!  Handbrake is the best open-source
video conversion software out there.  I don't know most of its
features yet, and haven't had a need to deinterlace or deblock video,
but a friend of mine is using the Mac version to digitally convert his
entire Star Trek collection into iTunes video format and he has to use
several of Handbrake's filtering features.
