I used to have have problem with mpc and EVR custom. videos were blurry. I changed EVR custom to EVR and the problem solved
a few days ago I updated my intel HD 3000 driver and after that videos are blurry again, even with EVR
before, when I switched from evr to evr custom I could clearly see the difference but now they are the same

ps. I'm not certain if driver update messed it up but i'm pretty sure it happened after driver update
ps2. I unistalled the driver and rolledback to previous diver and all the setting back to normal but still the problem exist
