I want to repeat something I noticed about 24p and auto under 2.8 on the XA2.
My display does report that it supports 24p and successfully worked with 2.7 to display 24p when the XA2 was set up for it.
Now, under 2.8, when the XA2 is set for auto, and it is displaying the set up screen for the player with no disc in the player, it does indeed send 24p to my screen. When I start up Harry Potter 5 (the only HD DVD I currently own) the XA2 switches to 60p.
I have a theory about the problem. My theory is that the player "auto" detects the source material frame rate and sets it immediately when the disc starts up and it does not check or change this setting after the initial setting. Unfortunately, most commercial discs contain all sorts of intro matieral that is likely recorded in 30p, causing the player to go to 60p mode, so once the disc starts we are stuck.
I hope Tosh will fix this in the future.
