You should download the replay files from sendspace and then place them in the replay directory of your game. (Use Percy version to watch replays, as currently the launcher version has a bug in its player)

Edit: just saw you figured out this one. lol


Regarding the 2nd you'll need some kind of screen capture software. You play the replay and record it with the software. Then you upload the video to YouTube.

to put video's on youtube you can use the most basic recording software, a popular free and decent one can be found here, and yes this download is trusted. I used to use Hypercam all the time.

No problem, Locked
