AVI's don't play in Sony Vegas

[Sky Captain]

I don't know how many here use Sony Vegas 7, but whenever I load an AVI file into it, the video stream cannot be attributed. The K-Lite Codec Pack doesn't do anything, so I'm not really sure how to fix this.

Anybody here have a solution? t:

To find out what codec the AVI file is using download this prog called Gspot just open up the file in this and it will tell you what is using what frame rate it is the whole 9 yards, once you find out what it is (xvid ect) google the codec and download it.

Download the c.c.c.p pack. It works for pretty much everything.

Oyyyy. Codecs are downloaded. Codecs are correct. Yet for some reason, Vegas still can't determine the stream attributes. I must've tried everything Google could possibly find.
