Hello all,
first of all, thanks for this great piece of software. I started to look into XBMC a little bit longer now, and I got subscribed to this forum here now. :-)
Ok, here are my starter questions:
1) What is the minimum hardware requirement for the XBMC to run smoothly?
2) Can the VDPAU branch upload its GUI rendering to the graphics core as well or is a remaining task to the CPU?
I'm wondering if I could insert a passively cooled Nvidia GFX cards into a plain old Pentium 2 board and do some nearly fan-less system setup.
So, how much (or better how less) Watts do your systems burn typically?
Regards,
Marcus

Right now, I'd suggest a PCIe 9500GT as being about the best 'bang per buck' out there. You can get passive 9500's too. Regarding the P2 thing... damn - thats pretty old! If it has a PCIe x16 slot it would *probably* work.
The rest of the rendering has always been OpenGL, which is of course hardware accelerated.
I'm running a few systems, the most efficient of which plays back 1080p at around 70 watts. Others have run xbmc-vdpau on Intel Atoms at significantly less.

Ok, I found the Asus P5N7A-VM Mainboard with Geforce 9300, which should run fine.
I gonna run that with a Intel Celeron S-430, this seems to be a good compromise for some performance margin for MP3 encoding or so.
You're right, P2 is really old, but I have one here. :-)
I saw a regular PCI based VDPAU card somewhere these days. Eventually, I give this a try in this old mainboard before I spend more for the final configuration.
Thanks!

On SD content XBMC-VDPAU with VDR patch doesnt seem to use VDPAU acceleration.

Hmm, ist this only not implemented yet or even not planed to be working ever?
I've read the Nvidia announcement of VPDAU, and I did not see a limitation for HD content only. So, this confuses me right now.
Ok, my plan is:
- silent and efficient HTPC
- with a fancy frontend
- for MP3, DVD, Images and TV + PVR
- TV, PVR is based on a DVB-T card
Hardware setup will be something like this:
7.1 speaker system <-- Denon 4306 receiver <--(optical cable)-- XBMC --(720p or 1080i HDMI)--> Toshiba 37" LCD TV
So, is VDPAU not the right approach for this?

The first Google result for VDPAU tells you that VDPAU is a spec for GPU accelerated play back of "MPEG-1, MPEG-2, H.264, and VC-1 bitstreams." That means it will work for most (if not all) HD formats and SD, as long as it's MPEG. VDPAU should work fine for DVB-T.
