That is true, sometimes. This is where Windows Media deviates from, and is imcompatible with, VC-1. On the other hand, having subsetted Windows Media and run it through SMPTE's rubber-stamping process, Microsoft will support all of VC-1 and more. So future Microsoft products will be a superset of SMPTE VC-1. Embrace and extend never sleeps. -----Original Message----- From: opendtv-bounce@xxxxxxxxxxxxx [mailto:opendtv-bounce@xxxxxxxxxxxxx] On Behalf Of Tom Barry Sent: Wednesday, January 12, 2005 6:23 AM I read somewhere once on the MSFT site that they encode in 4:1:1 when you say you want to keep interlace.
