Why not just put the video on Youtube or another video sharing website? No one is going to download that RAR for fear of viruses and keyloggers.
For one mediafire scans everything for viruses to ensure no one gets something they did not intend.
Second youtube in my opinion is trash. They re-encode the video and it distorts and becomes low quality and small resolution. My videos are as crisp and clean as if you were actually playing the game and are in hi resolution. I also compress them in a rar so that the download size is as small as if it were compressed with a codec like you tube uses yet you do not lose all the quality in the process.
I hope that answers the question of why they are the way they are because I know your not the only one who wondered but yeah there are reasons for why I did it this way.
On another note I have been covering the event like this since the beginning and there have been quite a few downloads of my various videos so by now I would hope I have some bit of clean rep going for me lol.
