[QUOTE="Owlsroost, post: 720719, member: 83973"] What you are seeing is quite common - the video is flagged in the stream headers as 60i but it's actually encoded as 30p - the 'Detd FPS' value is calculated in real time from the incoming video stream sample timestamps and it's approx. 30 fps in this case (as expected with 30p video). The 'Act FPS' value is calculated from the rate that samples are 'presented' for display, which is the same rate as 'Detd FPS' normally (but can be lower if there are performance problems causing dropped frames). If the video was really 60i with hardware de-interlacing, 'Detd FPS' would show approx. 60 fps instead. Tony [/QUOTE]
