Now i realize that a 333mhz model lombard powerbook doesnt have support on the motherboard for playing dvd movies, only the 400mhz model does. i was reading online that when it was new you could get a 2x dvd drive with the 333mhz model. now my question is, even though the 333mhz model doesnt support dvd playback because of a lack of a onboard decoder. would a combo dvd/cdrw drive in a 333mhz model still allow you to install software off dvd's or not? i know you couldnt watch any movies, but i would think you could still install off dvds right or read ones with data on them?
