Oh NOES! Well that happened to me and its still happening now...

What are the codecs for those media offline videos?

I use two codecs: Combined Community Codec Pack from XHunter's site and K-Lite Codec Pack 2.75 Full. Without the K-Lite, I couldn't use some of my cilps. I don't know much about Sony Vegas 6.0, but the K-Lite might help.
