These are two very good routers that I've only heard good things about:

First install winrar, this should associate rar files with it. Double click the cd 1 rar file and extract it, it will probably contain some type of iso. Use your burning program like Nero to open the previously extracted iso and burn. Repeat for cd 2.
You either need to extract the files from the rar (think of rar like zip) file or burn the rar files directly. There will be 2 cds that you have to burn.
Lol I can't belive I didn't realize this, you're clicking on the torrent file, not the actual video. Go to wherever you saved the file with bitcomet and try to open it.
