I tried the latest Jaunty alpha Kernel, with the latest XBMC SVN and...
well not so obviously like with Intrepid but still the performance is a lot worse. A lot of dropped frames with the 1080p content played without a dropped frame on Hardy.
I really can't belive that even with a 3Ghz Core 2 Duo CPU one can not play a 1080p movie without droppped frames, whilest the same movie is perfectly playable on the windows version of XBMC on a 2Ghz CPU with 70% utilization.
If i do the math, i can not come down to any other problem that (whatever the core utilizations show in XBMC) the video decoding is working single threaded on kernels newer than 2.6.24. I still think it is some compile option we need to change for ffmpeg to cope with the new kernels.
