Setting an option in /boot/config.txt overrides the auto HDMI mode, so it's be easy to force 50Hz (it'd be even better if it could selected on demand at runtime). Composite defaults to NTSC but can be configured as PAL too. I'll probably still need to implement some sound scaling to keep it in sync with the vsynced video. I'll also need to adapt the existing OpenGL code to use OpenGL ES for hardware acceleration. Regular OpenGL seems to be stuck in software mode (glxgears gets just 16fps!). The bundled GL ES demo ran perfectly smoothly, of course. On the sound side, the current ALSA driver is still very buggy. Using it gives a kernel 'oops' when anything tries to use it, so we might have to wait a bit longer for that. Si
