So, this project is a fair ways off for me, but I plan on trying to update my favorite game of all time, Riven, using all the original assets. The only problem I foresee running into is that as far as I can tell, Allegro only supports OGG video (theora + vorbis) and the Riven videos are in .mov format. So, basically, short of converting the files (which I largely don't want to do because of the likely quality loss that would inflict), what would my options be?

Thanks in advance for any suggestions! I'm asking this so far in advance of actually being able to implement it because the question has really been bothering me.
