180.29 VDPAU?

I've just built a PC with a ASUS M3N-H/HDMI. VDPAU is working, still some testing and tuning to be done.

I can view TV3 with around 12%CPU usage on one core. I have some bad blocking on fast moving objects on TV1, 2 and 3.

Cheers

Steve

I'd skip the 780G chipset and go for one that uses a NVIDIA 8300, or 
9300/9400 video chipset so you can actually use VDPAU as I do not recall 
the 780G as supported by VDPAU.

I am currently thinking about a ASUS M3N-H/HDMI ( 
http://www.asus.co.nz/products.aspx?l1=3&l2=149&l3=676&l4=0&model=2181&modelmenu=1 
<http://www.asus.co.nz/products.aspx?l1=3&l2=149&l3=676&l4=0&model=2181&modelmenu=1> 
) as you can set the video memory to 512MB which is the minimum you 
require for the current VDPAU support, you can get this for under $188.

Does anyone use / tried this one for VDPAU??

If you go for the above, I'd keep the PVR150 for the analog MPEG2 
encoder, dump the BTTV card (save your CPU cycles) and get a Hauppauge 
Nova-t 500 dual DVB-T tuner so that all your front end tuners deliver  
data that can be stream directly to your hard disk with minumal CPU 
overhead.  If you use a VDPAU compatible video card with 512MB of video 
RAM then I suspect you can get away with a  lower powered CPU, provided  
you do not want to do lots of simultaneous recording, playback and 
commerical flagging at the same time.  I'd recommend you get a low end 
AMD dual core and upgrade if and when you need to.

Cheers
Douglas.
