Previewing Files
 

I know i can't preview any files before downloading, but why can't i preview some VIDEO files that I'm downloading and have some percent downloaded already.:confused:

You should be able to if you've downloaded a certain % AND you have a player that can read that particular video format. It may also depend on your player whether it can play an incomplete video file.

For a standalone player with built-in codecs & plays all except the odd wmv file get VLC (it's free!): http://www.videolan.org/vlc/ (choose nearest mirror site)

If you need more codecs for your present player, see: http://www.divx-digest.com/software/nimo_pack.html (Choose Mirror 2 link ONLY!)
