I just released PPCMC 7.2.6, and I have made the first ever native Intel build of PowerPC Media Center 7. I had to figure out myself how to fix FFmpeg to compile on Mac OS X 10.4 Intel (PowerPC was just fine). And then... I got all x86 assembly optimizations enabled in the FFmpeg/FFplay and Panther_SDL2 builds. I threw a modern 1080p H.264 MKV with high bitrate at the Mac Mini Core2Duo 2.0 GHZ - 1GB RAM - Mac OS X 10.4.11 and it ran perfect. So did 720p YouTube streaming.
There does seem to be some kind of issue if surround sound audio is in videos. But using the PPCMC 7.2.6 "Open Media File" option to play a video in FFplay gets you an insane amount of performance with modern video codec support on Intel Tiger.
