Would it be too much to ask for OS9 compatibility?

Does he happen to know linux? If he can make a linux port, it will most definitely maybe probably work for a mac.

Then again, I'm a bit unreliable, as my Mac experience is mainly on 68k macs (AKA "The Crappy Grey Box"), and I only got my Mac G3 server (running OS9, a good upgrade from what it was shipped with) a couple of months ago. My experience with Mac is playing around with them at Fry's.

However, I do read a lot of wikipedia, and have plenty of experience with UNIXish systems. Mac OS X is built on top of Nextstep, which uses Mach - It's UNIX-based. I'm sure that gtk has been ported, and I know for a fact that Qt works on it.

On that note, it might be a good idea to rebuild it for Qt, which makes portability a matter of ease. All you need to know is C.
trolltech.com, by the way.

Then again, most of my argument is pretty baseless because I have no idea what's in a .torrent file.

Pointing out the obvious…

Leave the resolution the same as the origin, encode the video with h.264/x264. Best audio compression is with Vorbis, so using the Matroska container is wise.
