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

I'd skip the 780G chipset and go for one that uses a NVIDIA 8300, or <br>
9300/9400 video chipset so you can actually use VDPAU as I do not
recall <br>
the 780G as supported by VDPAU.<br>
<br>
I am currently thinking about a ASUS M3N-H/HDMI ( <br>

) as you can set the video memory to 512MB which is the minimum you <br>
require for the current VDPAU support, you can get this for under $188.<br>
<br>
Does anyone use / tried this one for VDPAU??<br>
<br>
If you go for the above, I'd keep the PVR150 for the analog MPEG2 <br>
encoder, dump the BTTV card (save your CPU cycles) and get a Hauppauge <br>
Nova-t 500 dual DVB-T tuner so that all your front end tuners deliver <br>
data that can be stream directly to your hard disk with minumal CPU <br>
overhead. If you use a VDPAU compatible video card with 512MB of video
<br>
RAM then I suspect you can get away with a lower powered CPU,
provided <br>
you do not want to do lots of simultaneous recording, playback and <br>
commerical flagging at the same time. I'd recommend you get a low end <br>
AMD dual core and upgrade if and when you need to.<br>
