Btw... I'm really curious to see the Slim XBOX DVD drive...

Edit: Also a friend of mine who's a Xbox sort-of-Guru... told me that XBOX dvd's are CUSTOM , with CUSTOM power connector that also carry serial data for eject/load/etc, and they rotate the disk in the opposite direction a normal dvd/cd drive does so there is really no comparison at all.
That does soud familiar. I know dreamcast disks were recored backwords.
Haven taken a few xboxs apart they defo not slim or standard ide 40
