first i'll start with the specs
Win7 RC (7100) 64bit
ATI Radeon 4770 w/ Catalyst 9.6 drivers
Hauppauge 900H USB TV-Tuner
My issue is in 7MC I can watch 1,2, & 3 perfectly. However every other channel displays a black channel with audio cutting in and out.
I have drawn the conclusion It could be an issue with Microsoft Windows Media Foundation codecs and ATI.
Using MediaPortal I was able to view channels 1,2 & 6. Weird huh?
I tried replacing the foundation H264 codec with CoreAVC but alas there is no 64bit CoreAVC codec yet so this does not work.
Is anyone else experiencing this problem or has seen a solution posted elsewhere? I've raised this with Hauppauge themselves yet no luck.
Tempted to give build 7260 a go. I know it works fine under Vista & Windows 7 32bit. And there is no issue using an Nvidia video card
