Toshiba HD-DVD Player & DVDSP4
 

First thing to note:

1. The MAC DVDSP4 HDDVD on standard media IS COMPATIBLE. But it has an issue:

a) It appears that the menu is got an issue, you can't move around at all, so you have to open the little slider on the remote and select a chapter to make it work. (Bye Bye transitions, but I think apple will get that corrected)

It seems as though it can't play/view the menu layer!!!! if you know what I mean....the reason I say this is because you can see the menu except the overlays that let's you select chapters!!!!!!

b) Kinda slow to load, but boy!!!

2. Is better than watching Discovery Channel in HD, SUPERB!!!
