Order of downloading parts for torrents

Question

If I download a torrent (uTorrent 2.0.1), is there a way to tell the program to prefer parts on the beginning of the file (eg. so that I can play a video file while downloading)? Something similar to putting high priority on first episodes of a serial and lower on the later ones, just in smaller scale.
The problem here is not the player, VLC plays it anyway, but it freezes very often when the blank spaces are equally distributed...
Other client that can do it would also be considered a solution.

Answer 1

BitComet can do this for you.
(Look for the option: "(Slower but better for preview/watching)")

(uTorrent can't just to clarify. Maybe there are others out there, I know only BitComet.)
