good question. it may mention it in the motherboard documentation or the PC docs. mine don't make any mention of it; until yesterday i was ignorant - i thought that usb2 was usb2 and that's that. BUT this is not so. . . i bought a pioneer 109 and an external usb to ide case to house the 109 in. it works fine on both my destop PCs that have gigabyte pro 1000 mobos. but when i tried it on my asus p4533-vm based PC Windows said "you are trying to connect a HI-Speed USB device to a non-hi speed port..." and i said OK, shutup and install it you loser ! however ! max ripping speed of a dvd is 0.7x - 2hrs 21mins !
with usb 2 hi-speed everytthing works as normal and FAST.
as to shrinking, no, not unless u want 2 dvds on the 1 dual layer dvd
