How to check waveform of an flv Flash video?

I'd like to check the luminance and color levels of some Flash encodes I've made, but I can't put them on the Vegas8a timeline to preview with the waveform monitor etc. (Vegas doesn't understand .flv) Does anyone know a way to check the waveform and/or color parade of an flv video? VirtualDub maybe?

maybe recapture the flv using something like camtasia then reimport...
in any case, flv should retain a decent enough colour spectrum close to the original.. unlike wmv....

or output a swf file with no sprites and put that on the timeline

Well, I'd really like to check the precise levels in the flv file. Re-rendering via Camtasia or swf might introduce changes in color levels -- which would defeat my purpose.

I have encoded bars with Pluge, and can see what happens to blacks, but it's harder to see what happens to the whites and super-whites. It'd be nice to put 'em on a scope.

I'm trying to confirm what happens to color levels (Studio RGB/Computer RGB) in FlixPro, for various intermediate formats coming from Vegas (or direct from client). Does anyone know for sure? FlixPro isn't covered in Glenn's Color Spaces article.

I assume that YouTube's recoding to flv will be the same as for FlixPro, but I intend to confirm that, too.
