Well my HTPC project is coming a little further however a friend has told me of the woes he had with an AMD 780G chipset at the start of the year, displaying green artifacts throughout his video.

There's a Geekzone thread about the same time but nothing since. Anyone had any experience recently using an AMD chipset? The 785G has a very compelling feature set and a good price.

Nvidia is the better choice, ATI have ironed out most of their driver bugs but Nvidia still has better htpc support/features overall eg: working hardware acceleration for L5 profile H.264 encodes.

Cheers Ragnor. Nvidia board availability seems quite a bit lower. I'll have a hunt and see what's out there.

I built a HTPC using a 780G motherboard (Gigabyte GA-MA78GM-US2H) back in May this year. Hardware acceleration works fine, and I haven't encountered any problems with Freeview|HD.

I use the Cyberlink PowerDVD H264 codec for video and Monogram AAC codec and AC3 Filter for audio. I'm currently using ATI Catalyst version 9.7.

Ah yes I've heard you can get hardware accelerated playback of L5+ h.264 encodes on ATI hardware if you are using the Cyberlink decoder.

Are you able to play this file (below) fine? What is the cpu usage %?

This clip (the 'Bird Scene' from Planet Earth) is a good L5.1 super high bitrate MKV sample

Works fine for me in windows 7 media center after the last lot of driver updates.

CPU is still pretty high but I only have a 6000+ CPU in there which doesnt have whatever the fancy hyper thing is that the onboard needs for the good deinterlacing modes to work.

For any new HTPC if you want it to be future proof and not require any upgrades I would say go for this board. Asus M4A785G HTPC/RC paired with a one of the new Athlon II x2, x3, or x4 45w CPU's and you will have one small, quite, well featured HTPC.

I am an dedicated nVidia graphics card user, but the new AMD 5xxx series graphics cards allow bitstreaming over HDMI. AFAIK they are the first discrete graphics card that allow that. nVidia can't do it yet.

I think general consensus now is that AMD Catalyst driver 9.7 allow NZ Freeview HD to work without green screen issues.

Yes, Catalyst 9.7 has been a trouble-free experience for me - and before that 9.4 was OK as well.

However a couple of weeks ago I installed Catalyst 9.9 and started to experience issues after resuming from sleep - a quick roll-back to 9.7 resolved that.

Ragnor: What is the cpu usage %?

My HTPC spends most of it's time recording and playing Freeview|HD programmes. While playing TV3 1080i programmes the CPU (AMD Athlon 64 X2 5400+) runs at 5% utilisation or less.

That's running GB-PVR on Vista 32 using the Radeon HD3200 graphics onboard a Gigabyte GA-MA78GM-US2H 780G motherboard. I use the Cyberlink PowerDVD H264 codec for video and Monogram AAC codec and AC3 Filter for audio. I'm currently using ATI Catalyst version 9.7.

ATI is fine for freeview

If you go 780/785G make sure you get HT3 CPU and disable CnQ in bios

I used to have those green screens when trying to watch the likes of C4 with my ATI card, but these issues were resolved with a catalyst release probably about 4 months ago. The latest Radeon Catalyst release works fine for me.
