Video playback was great before, but Haswell is supposed to output proper 23.976. All I can say is movies look great

Still need to set RGB "Full" with xrandr to avoid crushed blacks. Infrared needs the fix mentioned before even with 3.12.

I was having trouble getting all the modes automatically set up, but using OE daily build (I'm running devel-20131109194305-r16358) fixed it and 23.976 playback seems flawless.

The modes as shown by xmbc-xrandr (not while playing, so 60Hz active):

Code:

<mode id="0x49" name="1920x1080" w="1920" h="1080" hz="60.00000" current="true" preferred="true"/>
    <mode id="0xaa" name="1920x1080" w="1920" h="1080" hz="50.00000" current="false" preferred="false"/>
    <mode id="0xab" name="1920x1080" w="1920" h="1080" hz="59.94020" current="false" preferred="false"/>
    <mode id="0xae" name="1920x1080" w="1920" h="1080" hz="24.00000" current="false" preferred="false"/>
    <mode id="0xb0" name="1920x1080" w="1920" h="1080" hz="23.97608" current="false" preferred="false"/>

Looking into drivers/gpu/drm/i915/intel_ddi.c and the values it calculates, I wonder if the 59.94 and 23.976Hz modes are even more accurate than these numbers show. The parameters for 23.976Hz mode should result in exactly 1000/1001 of the 24Hz mode.

I also had to set RGB range "Full". I think my receiver should handle limited range too (it doesn't matter which one I choose from my Oppo - both seem to display fine). Maybe the infoframes are not output correctly?

The daily build also fixed multichannel PCM output. This is looking very promising.
