Ok my specs are:
Windows 7 build 7229
Dell 24" (primary monitor DVI)
Sony 40V4000 (secondary monitor DVI -> HDMI)
Core i7 920
GTX 280 (with newset drivers)
X-Fi Titanium 7.1 analog out
I'm playing MKVs with FLAC. I'm using BSPlayer.
Firstly, I have a problem where movies will stutter constantly whenever Aero is NOT disabled. In Windows 7, EVR renderer doesn't disable Aero anymore, and therefore stutters. Trying to manually disable Aero just causes tearing. The same goes for any VMR7 or 9 renderer, doesn't disable Aero.
The only two renderers which seem to disable Aero are Internal Overlay Renderer and Overlay Mixer.
I'm using Reclock with WASAPI Exclusive, which works well. I'm also outputting 24hz to my Sony 40" 1080p screen. Reclock does CINEMA adaption to convert the 23.976 to 24hz, to prevent the stutter you get every 30 seconds or so if it is left at 23.976.
I'm having to use the Overlay Mixer renderer instead of Internal BSplayer renderer, because with the Internal, Reclock doesn't detect the framerate 95% of the time, it just says "No video stream found", and can't sync to 24hz. Overlay Mixer always shows the resolution and framerate etc so there's no problem.
Now my actual problem is - using the Overlay Mixer and BSPlayer works well for about 30mins or so. Then it will randomly start to stutter after that long length of time being fine. The way to fix it is to press pause, then play. Then it will be fine for another 20 minutes, or 1 hour, or however long it is before it decides to start stuttering again.
So my questions are:
1) Is this stuttering problem related to playing the movies on a secondary monitor?
2) Does anyone else get jerky playback straight away when Aero is NOT disabled for any renderer? Seems to be that way for me.
3) Is there any way to fix this stuttering with my current solution of Overlay Mixer?
4) Should "Slave reference clock to audio" be ticked or not? It currently isnt.
If I switch back to 60hz there isn't any problem. It's trouble-free. So if there isn't any solution to these 24hz issues, I'll just go back to 60hz. I still get the stuttering when Aero IS enabled though, that seems to be a general thing for me. Because of that reason, I liked how Vista disabled Aero for EVR renderer, Windows 7 doesn't
