sadly the mpeg decoder on the ati cards in imac dv's (and my ibook dual usb) are unsupported
thats the sole reason my old imac dv runs osx
man id be willing to throw cash at someone to reverse engineer it. pity ben is a busy man as it is. someone clone him.
Well, that's a little bit of a different situation. On the older Mac Powerbooks, with 64-bit ATI graphics chips, there was a dedicated MPEG-2 hardware decoder, either a PCMCIA card, or a chip on the laptop motherboard. I don't know if the 64-bit chip lacked the horsepower, or just basicfunctionality, to play MPEG-2 streams at the appropriate frame rate, but additional hardware was needed.
Yah, and it's not simple to make it work because you need both to have a driver for that chip, and to have a proper capture/overlay driver for the mach64 as the output of that decoder is a digital video stream (4:2:2 afaik) that is routed to the input of the mach64 chip.
Mines all on the ATI Rage card on the system board.
ibook dv and ibook dual usb, both with dvd roms, the ibook dual usb has a super-drive or whatever rubbish name they give to dvdrom/cdrw combos. someone beat some specs out of ati.
