MorphOS has got the best graphics driver for PowerPC's. I once tried to play a 720p movie on a Mac mini G4 and only with the MorphOS did it play smoothly albeit with the audio going asynchronous after 4-5 minutes.
So it's smooth but doesn't do synch properly? That's kind of a deal breaker – keeping in synch is (or should be) a higher priority than not skipping frames.
You're correct. But that was about 2-3 years ago when I tried it. That might have been fixed by this new release, perhaps.
That sounds amazing! I’d love to try MorphOS on my 20-inch iMac G5 (iSight)¹ which also struggles a bit with H.264 720p+ video (especially when using QuickTime Player, which seems to be pretty inefficient), but unfortunately, judging by the hardware requirements page², G5 iMacs don’t seem to be supported…
