XBMC+NVIDIA+DynamicTwinView = Wrong refresh rate

I was wondering why I got tearing with XBMC even though I had enabled vsync and why XBMC was reporting a refresh rate of 50Hz for my screen instead of 75Hz as it should have been. It turns out that NVIDIA’s DynamicTwinView feature reports a fake refresh rate (that of the MetaMode which encompasses all of the screens involved in the TwinView) which may not be the one for the physical device. As I am not using TwinView I added the following Option to my xorg.conf Device section:

Option "DynamicTwinView" "False"

HTPC photos

I promised over a month ago some photos of my custom HTPC, so here they are:

The front of the box showing the 20x2 LCD, the slimline Optiarc BC-5600S Blu-Ray/DVDRW and two of the USB ports

The untidy guts of the box showing the Zotac ION ITX motherboard on the right, the 700GB Western Digital HDD and the Slimline BD/DVDRW Drive. There are two 1GB sticks of DDR2 RAM under the optical drive. Notice the unused horizontal slots in the case at the rear of the box

The back of the case showing the multitude of connections: PS/2 mouse, USB Wi-Fi Siemens stick, optical S/PDIF output, HDMI, VGA, analog audio out and the DC power cable (the brick is out of view)

The box is running Ubuntu 9.10 (aka Karmic Koala) and XBMC which takes advantage of the ION’s PureVideo capabilities via VDPAU.
