Sampling, compression and mpeg-2

Now we know that DV isn't the way to produce the best video but if I want anything better then th n ext rung up the ladder is a BIG step. Firstly I need a better camera and VCR either DigitBetacam or DVCPRO 50, neither of those comes cheap.

However if all I'm working with is stills and generated media then I don't need to worry about the camera part of the equation and as I'm only going to DVD I can see no reason why I shouldn't get as good a result as if I was encoding from uncompressed HD at 4:4:4.

Is this a pipedream?
Does Vegas sample / compress to DV25 and feed that into the encoder?
Is there a way to feed the mpeg encoder uncompressed video?

Sorry if I haven't put this very well, hopefully someone who knows the answer will figure out what I'm on about.

Vegas decompresses all source material, applies processing, and then feeds the various encoders uncompressed frames. There is no interim compression step unless the user does that manually.
