I hope that they will release the source code soon so that I can play with it

Hi Stephan, I looked in the download section for the matrix, and they published some source.. I don't know if it is containing all the stuff you are looking for but here the direct link:
http://sourceforge.net/projects/matrixtv/

Hi,

I am not sure it is the case : There are only binaries in all provided archives.
Or I have missed them but I have really searched for them ! If you have found source code, could you point the archive name and the folder location in this archive ?

Anyway I am in touch with a developer at tbstv and they seem to be ready to address this issue with very good willingness...

Here more tests for the Matrix TBS

Conclusion: I would be nice to have some contorl over the Fan, just in case the temeprature goes so high, to turn it on (or leave it very low blowing). But I don't think xbmc would utilize all cores to 100%

Damn, that is bad news
Have you tried the same CPU bench without XBMC ?
I ask because it may be stable that way... Indeed, even if XBMC CPU load is not very high, the GPU and VPU (if you play video) produce their own quota of heat.
Maybe the pure CPU load can be dissipated without diverging if there is no other activity in the soc...

I have a good news : the fan can be controlled by a GPIO. I still don't know which one but we will know this as soon as the kernel is published !

Best regards
Stephan

Edit : apart from this you are right as long as VPU is used to decode video XBMC will never push the 4 cores to such a load... (And even for sw decoding , I doubt such load figures woudl happen. I am not even sure frame threading is enabled for ffmpeg in build )
