The MPEG2 codec expects a Broadcast Level input, i.e. RGB 16-235. If you encode with a signal that is RGB 0-255, you'll get an RGB 16-235 signal out, and, you'll truncate or clip any info above RGB235 and below RGB16. The resultant MPEG2 output will look washed out and low contrast, with mushy blacks and blown out whites. WMV, on the other hand, will pass thru whatever input signal you give it. So, feed WMV an RGB0-255 signal and you'll get an RGB0-255 signal out.

Hi, thanks a lot Bill, this would clear many heads, about this "problem" with MPEG-2, i cut my project in 23.97fps NTSC DV Vegas8 timeline with mxf files, CC & then output to a 24p NTSC DV MPEG-2 ready for DVD authoring (with pull-down flags embeded), make a progressive capable DVD with Sony DVD architect, doesnt look good!

REASON: the whites look clamped, the blacks are not 'black' my eyes strain watching them, maybe my not so good CC, any suggestion to make this better whith encoding /editing. Thanks

In Vegas, check the colour space set (Advanced Video tab of the "Render as..." template).
