Recently i bought a new pc, because my old crashed...
I have an Ezcap pci-e video capture and i use pot player to record stuff.
Since then when i press the right arrow button to check if is everything ok, the screen makes these black boxes as you see in the link below.
I didnt had these problems with my old pc...
Why that? Can anybody help me....Thanks!
