Just talk to Roger or Randall about the Bt848 driver because I am sure that both can help you. You are right that proper yuv handling in the Bt848 driver is important and I feel very comfortable that we can tackle the problem. What I am after is for the X server to do the yuv->rgb and scaling in hardware. The idea is to conserve as much as possible memory bandwith and in a full multitasking environment such as FreeBD to provide smooth video playback .
