From http://www.apple.com/support/releasenotes/en/Compressor_3.0_rn/

"Color Tab in Inspector
The Filters pane of the Inspector now includes a Color tab for selecting and adjusting color space settings.

This tab is available for the following QuickTime output file formats only:

H.264
Apple ProRes 422
Apple Intermediate Codec
JPEG

To select a color space setting, choose one of the following from the Output Color Space pop-up menu:
Default for Encoder: Compressor chooses the output color space based on the dimensions of the output file.
Preserve source: Retains the color space of the source media file.
SD (601): Forces the output file to the ITU-R BT.601 (standard definition) color space.
HD (709): Forces the output file to the ITU-R BT.709 (high definition) color space.

No, and it never was. The DVD video standard requires MPEG-2.

How exactly have you evaluated that the whites are blown out?

Sorry to repeat myself but, how exactly have you evaluated that the whites are blown out?

What scope or monitoring method are you using?

OK,

Sorry but that's not anywhere near exact. Your Mac laptop very likely uses a low quality (when compared to broadcast quality) TN panel and this is dithered from 6bit. "A TV set" could mean anything.

Sorry, I don't want to appear as being difficult but you are probably not using the correct gear to reach a correct judgement on how your video really looks. (Have you even calibrated your laptop display? What Gamma setting are you using? etc).

That aside, if you need to colour correct, then you should do this in FCP or use the more basic filters in compressor which are somewhat hit and miss.

Simple answer to the problem:

You can adjust your color values to more your liking through 'Filters' tab in the 'Inspector' window. I've had the same problem with the whites being blown out (no scope needed - you can SEE it with your eye on any monitor). I've gotten the best results from adjusting the 'Gamma'. But you can also use the common controls of 'Brightness Contrast'. I've also tried the 'BlackWhite' Restore, and that's pretty good if you want to get a 'crushed' black feel.

Hope this is more helpful!
