A) Sorry do not have a 24p capable display.
B) Yes, the BH200 sent DTS-HD MA 5.1 and DD THD 5.1 transcoded to LPCM to my HDMI v1.3 AVR so it should work with a v1.1 AVR as well. I could not tell the difference between raw and transcoded audio. Yeah, it was that good, tested with Kingdom of Heaven. Also my AVR identified the raw audio as 7.1 even when I disable processing, which freaked me out a little because the disc is only 5.1. I am going to play with it some more tonight to see why that is.
