Black video window or choppy video when watching a digital TV channel
If you are watching a digital TV channel and you see choppy video, no audio or a black screen, then it is possible your PC is not fast enough to decode and play the digital TV channel you are watching. Please verify that your system meets the minimum requirements for using the WinTV-dualHD
Digital TV, especially DVB-T/T2 high definition digital TV, is very CPU intensive. Many graphics cards have special built-in hardware to speed up decoding of high definition TV channels.
On graphics cards without special video decoding features, you can often improve the playback performance by using the Video Renderer settings located in the settings menu of WinTV v8. To open the setting menu click on the “gear” button located in the lower left of the WinTV v8 screen.
The default mode is EVR. The other modes are VMR9, VMR7 and Overlay. Each mode uses a different process to render video. Try each mode and use the one which gives you the best results. To use hardware acceleration put a check in the box “use hardware acceleration when possible. This will allow your graphics system to use hardware acceleration for video decode. Note: graphics hardware acceleration does not work on all systems. After making a change in video rendering settings Wintv must be restarted to take effect.
