Som det kan læses her, så har AMD's Brazos platform nogle problemer med nogle video materialer.
Det skal dog siges, at den lige nu gør det bedre end en WDTV Live Hub, så det er jo ikke helt skidt.

I ran MSI’s Brazos board through our Media Streaming compatibility suite. Below is Brazos’ compatibility score compared to the other devices and HTPCs we’ve put through the suite:

AnandTech Media Streamer Suite

Failed Tests

- 1080p60 60 fps L5.1 H.264
- L5.1 H.264 (16 reference frames)
- FLAC, ASS Subs - High CPU Utilization
- HD Real Media
- Deinterlacing

Numerically, Brazos actually falls behind ION. Allow me to explain why. Our Media Streaming suite tests virtually everything you might throw at a HTPC. When it comes to the most commonly found content, Brazos excels. It can handle Blu-ray discs (although there’s no Blu-ray 3D support), it can deal with 1080p x264s commonly found online and it even accelerates Flash video (more on this later). Brazos’ UVD3 however is tied to clock speed, and the GPU clock of the Radeon HD 6310 is pretty low at 500MHz. As a result, Brazos fails certain tests. The platform is incapable of accelerating and playing back 1080p60 H.264 video. (heldigvis er der ikke så meget af det) Very little content falls into this category, however if you want to play it you can’t on Brazos. The good news is 1080i60 works just fine.

Brazos’ GPU also fails all of our deinterlacing tests, something we noticed in reviews of AMD’s entry level GPUs. (øv) The higher end models don’t have an issue here but the lesser equipped models do. Again, chances are that you won’t want to watch interlaced content on your Brazos HTPC so this is likely not a big issue.

The other shortcomings are videos with components that aren’t accelerated by UVD3. For example, HD Real Video chugs on Brazos as does our heavy FLAC + ASS subs test. If you’re playing non-3D Blu-ray content or 1080p24 x264s you find on the web, Brazos will easily fit the bill. It’s the more eccentric content that you’ll run into CPU limitations with.

De fleste af tingene er noget som sikkert kan løse gennem bedre driver fremadrettet.
AMD's Brazos platform har mange ting der taler for den, men kan du vente - så se tiden an.

Jeg ved stadig ikke hvad materiale der ligger som 1080p60 i AVC/H.264, så det må være en meget lille begrænsning - måske er Anandtechs test overkill.

Vedr. deinterlacing, så er det dog mere relevant her i DK end hos Anandtech i USA: DR1, DR2 og TV2 udsendes alle interlaced (med 25 Hz) via DVB-T/C - indtil 2012 i hvertfald.

Min konkrete erfaring med AMD Brazos/Fusion/Zacate/Ontario: Med et ASUS E35M1-M PRO bundkort er det intet problem at deinterlace MPEG-2 (DR1, DR2 og TV2) via software (XBMC på Linux). CPU-forbruget holder sig under 40% (og det er uden hardware acceleration). Med MPEG-4 (DR K, DR HD) kommer CPU-forbrug ned på 15-20% (der er dog ikke behov for deinterlacing).

Det er godt at se at du er glad for din Smile

Hvad med deinterlace på Mpeg4 div. mkv, avi filer med forskellige codecs?
Du må meget gerne lave nogle grundige test, så vi også kan få en danskers øjne på "svinet" Smile
 
De ting som du fremhæver, er tid som bare skal være i orden!
Det spændende er jo de ting, som ikke virker endnu. For hvis det er en vigtig ting for ens brug - så er det blandt andet dem som afgøre om det er et godt køb eller ej.
