I've been playing with XBMC - both XBMC Live and Ubuntu 9.4 32bit and XBMC on a home-built nVidia 9400 IGP system with 4GB of RAM, 512MB allocated to the video system, an E7300 CPU via HDMI. Currently running the nVidia drivers that are downloading (180.something) via the restricted hardware driver bit of Ubuntu.

However I'm getting loads of freezing, and video corruption. Often when I maximise Firefox I get a total video crash (garbage video, sometimes the pointer moves sometimes it doesn't etc.)

Has anyone else had these problems?

I've been using the same build hardware for 6months + with no problems with Vista and Win 7 RC 32bit - and had no crashes or problems there...

Thoughts?

Done quite a lot of searching - and it seems some people have had issues but not pinned them down?

You probably need newer drivers to start with
and to enable VDPAU

NVIDIA Drivers
--------------
Edit: Install nvidia PPA instead to avoid problem when upgrading kernel
https://launchpad.net/~nvidia-vdpau/+archive/ppa

NB: I have not tried this on a clean install, only after removing the manually built driver.
If the xorg.conf is not configured maybe this need to be run "sudo nvidia-xconfig".

0) Remove manually installed driver
sudo /etc/init.d/gdm stop
sudo /usr/bin/nvidia-uninstall

1) Add source
sudo nano /etc/apt/sources.list
deb http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu jaunty main

3) Add key
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com CEC06767

4) Install
sudo apt-get update
sudo apt-get install linux-headers-generic nvidia-glx-185

5) Config
sudo nvidia-xconfig -s --no-logo --force-generate

and you should probably disable the ubuntu restricted driver first

Brilliant - many thanks for that. Whole system is MUCH more stable as a result.

Now I just need to work out how to get Temporal de-interlacing in VDPAU to de-interlace 50i to 50p not 25p...
