I'm trying to stream Netflix on an Acer Revo 3700 running Windows 7 Home Premium, but it hangs on the loading screen at 98% (after it has formatted the player to the right aspect ratio and added the controls, but before the video starts) with no error messages or failures.

I have two other machines on the same network, one running Windows 7 Home Premium and another running XP, which both stream faultlessly.

Things I have tried:

• Both a wired and wireless connection to the router
• Upgrading the video and audio drivers
• IE, Chrome and Firefox
• Boxee software
• Connecting with a VGA cable instead of HDMI (in case it is a HDCP thing)
• Uninstalling and reinstalling Silverlight.
• Getting someway into loading a HD movie and turning "Allow HD" off

Does anyone know what Netflix is doing at the 98% load mark? Are there any log files? Anything else worth trying?

Full disclosure:

I'm using Netflix from the UK through a US based VPN. I've tried multiple VPNs and the problem is exactly the same, also the other machines on the same network through the same VPN work fine so I don't think this is the issue, but it might be a factor. The region check happens at around 7% and I get past that.
