Wait. My answer was a reply to your question about what that "deviation" information in the OSD means. 24p@60Hz is a different topic. The simple problem with 24p@60Hz is that 60 is not a simple mulitply of 24, which means that every renderer out there today shows a 3:2 motion judder. Basically frame A is shown for 2 vsync periods, then frame A+1 is shown for 3 vsync periods, then frame A+2 for 2 vsyncs, frame A+3 for 3 vsyncs, etc. This uneven frame repeat pattern results in that motion isn't perfectly smooth.
