Well, this is a weird one. Normally I am able to use TS files on Sony Vegas. I had one saved onto my external hard drive, that works perfectly on Sony Vegas. However, I downloaded another file, which is completely different. When I have Shark 007 installed, windows media player doesn't show me the moving picture (just the audio), and when I drag it to Vegas, only the audio pops up. Also, the first file I am talking about has a perfect thumbnail, whilst the file that's causing me problems has the default thumbnail.
