Does TVMW do any kind of dithering when converting 24-bit to 16-bit audio (LPCM) ?

Dithering is also a question in some video conversion scenarios: see my previous post about this: http://bbs.pegasys-inc.com/bbs/list/lang/en/board/TVMW5/keyword/dithering/topic/69535#topic69535

Hi

I wonder how 10-bit sources are subsampled to 8-bit during conversion ?
Just plain stripping of the LSB ?
What implications on how to best prepare the 10-bit source (dithering ?)

Maybe inrelated to the above Q, but I was making some tests with a jpeg2000 encoded video (4.2.2, 10bit, Avid implementation) in a QuickTime MOV container, and noticed that the luma range was incorrectly detected by TVMW (needs significant contrast & brightness boost)
