And what git version do you use ?

Hi Gimli,

I assure you CPU is very low on all builds after May 30. On the specific one I tested revision was:b2f7a0d97fd0feb928fdc689c8aa01772b040451

but also verified on June 8th nightly I compiled.

Using these patches for LIRC and WebServer: http://svn.stmlabs.com/svn/raspbmc/patches/XBMC though they do not make a difference on performance I'm sure.

Just went into Raspbmc pressed Debug Logging and got 24.6% CPU usage (up from 16% because it is writing the fps output each second). Still, this proves top output is true!

Ask the question in the Rpi topic. If it runs nicely or just about nicely then yes, it will run nicely at the A10 as well. When you are at it. Ask them to checkout the Lightbox skin as well.

Asking the question in this thread as requested.

Could anyone tell me what the performance is like with the Quartz or xTV-SAF skins? I am wondering if they are light enough to run on the RaspberyPi and presumably then also on the Allwinner devices? j1nx would also like me to ask if the Lightbox skin performs as well or better than those two or the default skin.

Thank you for your time.

I'd like to play 1:1 rips of my blu rays stored on a Windows Home Server over wired network. They mostly have dts-hd master audio. Is this possible with the current builds on the Pi?

Only if you have a DTS capable receiver, so you can pass it through. The RPi is not strong enough to decode Video & DTS audio at the same time.
AC3 seems to work, other than that, MP3, OGG Vorbis & AAC are the way to go !

Thanks Sebert. I have a dts-ma receiver. I thought the 30gb 1080p video file might trip this little fella up. Perhaps I should get one anyway, my last xbmc update on my Xbox one was years ago. Still used daily by my daughter to watch her film collection though. Time I was back on the bleeding edge - stability is overrated!

Has anyone tried the CEC support for the RPi? Is an adapter needed, ala the PulseEight CEC adapter, or will it work out of the box?

Simon156 Blu-ray's come in MPEG-2, VC-1 and H.264 flavours, the R-Pi only has hardware decoding for MPEG-4 and H.264 video so BD's in those other formats wont be playable.
