Hi Folks, I need some help to solve a minor bug...but preventing my "perfect" HTPC.
Let me start out by saying I have no issues with playback -- DVD or Blu Ray -- of any kind, neither do I have any audio issues over HDMI (I get great sound to my Onkyo...DD, DTS, and 7.1 / 5.1 LPCM).
My issue is a different one...
I have 2 different 8200 MB's (Asus and ECS). I also have the Asus 8300 MB (M3N78 Pro). And I've been playing around...
The 8300 gives me 100% smooth playback on Vista Media Center (Ultimate SP1 32 bit) when watching ripped DVD's. It also gives me stunning, 100% smooth playback on Blu Ray played using Power DVD 8 Ultra. I have Aero disabled so I don't get the annoying message when I play Blu Ray.
The problem I need help overcoming is screen tearing when I enter Vista Media Center (when I press the green button). Upon launch the screen tears and flickers fairly badly...most notable when I move around the interface but also flickers when it just sits there. My family is abusing me for this little annoyance and I just don't know how to fix it.
I am connected via HDMI to my Onkyo receiver and get fantastic sound...so no issues there.
The 8200 boards where very bad but had the problem as I'm having with the 8300.
I am using a 4850e, 4 GB GSkill DDR1000 memory, and monster cables. I have it connected to Samsung 46" 1080p LCD through my Onkyo.
I do not have this problem on the Gigabyte board with the ATI on board video but lack of 7.1. LPCM prevents me from using it in my HTPC...but at least I know it's not CPU or RAM or TV or Onkyo.
I've put in an MSI 8500GT card and used a DVI > HDMI cable and the tearing goes away so I don't think it's a driver issue...I've also stuck in an 8600GT and again picture perfect.
I then stuck in an ATI 2600XT and also tried an HD3450...both using HDMI for audio/video and once again, picture perfect! And sound from HDMI (albeit only DD or DTS no 7.1 LPCM).
Therefore, I've eliminated everything out of the equation other than onboard 8200 or 8300, so I really need your help...how can I get rid of my screen tearing in Vista Media Center interface?
BTW, I've tried OC'ing...steady, but still tearing (no better or worse). I've tried turning off CnQ...no problem, same tearing (no better or worse). I've set all onboard processor-related settings to auto...same problem (no better or worse). I've set them all manually to correct settings (and even higher/lower just to test), and same problem (no better or worse). I've also tried with 3 different Vista installations...same problem.
So in summary, on my 8300 board (even though I had the same issue on my 8200 board) the only problem I'm left with and need you help fixing is the darn screen tearing in the VMC interface...everything else is 100% good.
I'm losing hair...so I need your help
EDITED: I've tried 174.xx drivers through the current ones and all BIOS options...same tearing/flickering in VMC.
