I have looked on google ... and not found any solution.
My Computer:

core i5
4GB RAM
500GB SATA
GTX 460 1GB DDR5

I bought the AVerTV HD DVR, I installed the driver and software. When I start Avermedia Center and select HDMI, the image has horizontal lines and flickering.

I made a video for you guys to see:



I used other programs and continues with the same problem
Please can someone help me?
