Help with correcting mpeg encoding

Hello Helpful People,
I have a video that was shot in DV with strong overhead lighting with very little overall lighting. You can look at a still picture at

scroll down to the second picture, I'm playing the gold tuba. The video looks ok in Vegas 6d, ie faces have color and the strong overhead lights don't bleed out the faces. When I encode to mpeg(DVD Architect video stream template) the faces of people that have a lot of light on there heads turn into white blobs and the whole scene turns dark. I don't know if I need to make changes to the encoder settings or try some fx in Vegas. Any thoughts would be appreciated.
Thanks
Bill

You would have to mask areas out to correct this using Vegas, but first I would try a CBR of 8000 and a DC Coefficient of 10 when you render the video stream to Mpeg 2 using the DVDA template.

Thanks John for replying. I usually set to CBR 8,000,000 when I have the space to play with which I did for this project. I didn't try to change the DC coifficient, will give it a try. Masking might be hard to do as the camera wasn't stationery. I have tried playing with the levels fx and changing the gamma setting and also the brightness and contrast. I've tried many different settings on a small clip and haven't hit any that fixed things.
