I'm with edemiere on this one...only because I'm used to the fat32 system and all you can do from dos if trouble arises. I also do some video editing and have not run into the 4 gb limit...yet! However, if you have, or will have issues with file sizes then NTFS is the only real solution.
As for security, NTFS again gets the nod, I've setup pc's that appear nearly hardwired with w2k and NTFS...something that would have been much more difficult in fat32, if not impossible.
Stability, well I'm of the school that w2k and xp are much more stable than win9x but that is an OS issue rather than NTFS vs fat32.
Speed is relative, I run both NTFS and fat32 on the pc's I own and the only real speed benefits come from fast equipment and/or a well tweaked system OS.
My personal pc runs XP Pro on a P4 2 ghz with fat32 where as my server is a w2k PIII 500 hz with NTFS. Both systems are stable and secure. The XP system is obviously much faster and I do every thing from gaming, email, web, video editing and burning. However I use my w2k system to watch videos on my TV and it does so without any real problems. You're milage may vary!
Cheers
