Display and Audio Problems on Mac Mini

(1/2) > >>

park:
I have a 2012 Oct Mac Mini with Win7 installed in Bootcamp. Totally clean install, with MC the only software I have installed on it. The Denon reciever it goes through is a 24bit 7 channel capable, hdmi connected reciever. The computer outputs a 1280x720 res desktop but I use the Intel Display software to scale the image down to compensate for the underscan on my TV so that I can see the Start button. I scale down to 60h and 55w. Occiasionally in the action center it tells me that this resolution isnt "optimal" but I can't think of anything else to do. I am having the following problems:

1. Since build 181 any movie file with multichannel audio wont play. Worse, it crashes MC immediately. The files are h.264 mkvs with passthrough dts or ac3 audio. I have bitstreaming turned on in options, but turned off for dts-hd audio because my Denon reciever can't deal with it.

Build 180 with WASAPI output and bitsreaming turned on works fine.


2. When I start the computer up and it starts in Theater View mode all the icons bunch up in the top left of the screen. If I try to escape out, I get taken to a random View in Theater view but can't navigate up to the rollers. Also, from that point on I am unable to escape of of Theater View or do anything at all except navigate the current list. If I start a movie in the list the screen wont go to Display view. The movie audio plays in the background.

3. A similar problem happens when going from Display View to Playing now then back to Display View. The interface freezes trying to go back to Display View and I can't escape out or do anything except ALT f4 to close the whole interface.

I had to search for it but I thought I read about this elsewhere as well:
Find the option "Quantization" and set it to Default or Full.

park:
It would appear that that Quantization option isnt in the latest intel drivers. As I read it, that only affects the rgb range being sent out anyway. I wonder if that would be enough to mess with MC's full screen mode.

Generally the first time I launch Theater View I see all the icons bunch up in the top left and overlap. If I then ALT f4 out and then launch it again Theater view becomes perfectly fine and usable from that point on.

glynor:
The best choice is to fix the underscan/overscan on your TV Set.  Any other method makes the resolution actually non-optimal (it has to scale it, which makes hardware pixels no longer map to points in the OS, which seriously degrades quality).

What kind of TV do you have?

park:
Sony Bravia kdl-32v2500

Haven't seen any settings anywhere in its menus for underscan.

Perhaps I could try a few days of letting the screen crop a little, and using the unscaled 720 resolution of the graphics software, just to see if the scaling really is the root cause of MC's weirdness regarding Theater View.
