Hi.
I have a Raspberry Pi 512MB version running the latest Raspbian “wheezy” (2012-12-16) with the latest firmware on it ( https://github.com/Hexxeh/rpi-update ), uname -a show: Linux raspberrypi 3.6.11+ #358 PREEMPT Tue Jan 15 00:45:33 GMT 2013 armv6l GNU/Linux. It's overclocked at 950 MHz, I have also hdmi_force_edid_audio=1 into config.txt file.
On it I installed XMBC Frodo RC 3 ( http://michael.gorven.za.net/raspberrypi/xbmc ) and it works well.
I use XBMC for play .mkv files (1080p also with DTS), I open the .mkv files on XBMC via smb (windows share); but when there is a high bitrate the video and audio became stutter. The problem, I think, is that the bandwith is not enough. Consider that the Raspberry Pi is connected via cable ethernet on a Gigabit switch and also the Windows PC (which shares the files) is attached on the same switch. Looking into Windows PC Task manager I noticed that the maxium peak of bandwith of the ethernet is "only" 5% of 1Gigabit (so 50% of 100Megabit) and may be (better for sure) this throughput is not enought for streaming 1080p high bitrate file.
Look also at this image, this is the network throughput during streaming mkv file from PC to Raspberry (the values are referred to a Gigabit so multiply by 10 for 100Megabit).
As you can see the throughput is very low..... and it's not enough to watch mkv.
SO, now, How Can I solve? There is a way to use more ethernet bandwith on the Raspberry?
There is the possibility to say to XBMC to increase the buffer?
Thanks!
