Yes, the osds were fine - I assume you mean during playback?  Everything just worked.

No idea. It's a small form factor HP business pc that I got from work when they were selling them off for 30 as part of an upgrade. 

I did have a fiddle around with the various settings in the bios but never managed to find a combination that worked. I think I ended up wit the on board graphics disabled, an old-ish nvidia agp card and the Sparkle pci card in it. That's the only way it would boot!  The bios and text console display on the agp card and I configured X to run on the pci card. 

Sadly the agp card wasn't new enough to do vdpau and I couldn't find a low profile agp card that would. Thankfully the pci slots were turned on their side it would take a full height card. 

The only other problem was that the massive heat sink on the pci card blocked both if the pci slots.  Hence it was a frontend only. 

I've not actually used it for ages, but I'll bring it back into service at some point.
