DxTory plugins... or what?

[LinkPK]

Hi! I am YouTuber and partnered. My contract says that I have to upload at least 2 videos per month, but now, when I record, I can hear both audio tracks but I cannot see the video. I tried with Windows Media Player, Media Classic, DivX Player and more, but nothing. When I drag the video to Sony Vegas, it sends me an error like "Sony Vegas cannot read this file" or something very close to that. I tried installing some video and audio plugins like ffdshow and cccp and more, but nothing. It's nothing about Dxtory config because I have the same videos than before formatting my PC, and I don't know what I'm missing in my PC. Can someone help me please? It's really important.

Thanks!
