I've recently set up my HTPC so it can be used in 2 different rooms. To do this however i had to run a 10m HDMI to the receiver and then a 10m to the TV.
My amp is an Onkyo 576 which says it has hdmi repeating.

Since connecting it up i get jerky video playback when running Windows7. However, when running XP (dual boot) the playback is still good.

Does anyone know any reason why this might happen?

Could Win7 be outputing a weaker signal or something? I guess any hints for Vista might be appropriate too.

Thanks!
 
It could be the Windows 7 video driver, still early days for that.
What video card do you have, maybe others have experience with it under W7.
The signal level is determined by the electronics on the video card.
 
I run my laptop to my HD TV, using a inexpesive 12m HDMI cable i bought of eBay and have no problems whatsoever using Vista.

So the the amp definitely acts as a repeater? not simply a passthrough? as at lengths of over 15m, they are recommended.

cheers for the replies guys.

Yes, receiver is definitely a repeater, well it says it is in the manual.

My graphics card is an onboard nvidia 8200 running driver version 181something.

I've noticed that the image quality is much better on XP too, so i'm leaning towards some sort of driver issue to be honest.
