Different chipset (the little CPU inside the drive). And probably different laser. And even if the hardware was indeed all the same, there could be other problems. For example, Philips's drive can be firmware-upgraded to do dual-layer, but Philips says that it's possible only on a few select units with exceptionally good pick-up-heads. Basically, don't hold your breath for a 812->832 upgrade, as it's looking like it's quite unlikely. But the 812 does have a slightly better shot at it than the 811.
