Intel Graphics HD 4000 problems with 1080i video.

idata — Tue, 05 Jun 2012 13:24:33 GMT

I use Windows Media Center (new HTPC) to watch TV:

Motherboard: Gigabyte G1.sniper M3

OS: Windows 7 Ultimate 64bit

CPU: Core i7-3770 / T

GPU: Intel HD Graphics 4000 (CPU on board)

In live TV channels or playback of TV recordings with 1080i-resolution TV image is choppy for about 1 minute. After that everything is fine. The problem is not present at 720p resolution. Only at 1080i.

I installed the latest driver 8.15.10.2696.

Please help. Thank you.

I can confirm. Have the same problem on ASUS DZ77-V board, otherwise identical config as yours.

Seems interlaced handling is broken in this driver.

Have the same issue with config:

CPU: Intel i3-3225 (HD4000)

MB: Biostar H61MH

Driver version: 15.28.8.64.2875 (x64)

When I switch DXVA2 mode to DXVA in registry, all works fine but with higher CPU usage.

It seems that it's 100% driver issue.
