The first 3 bits specify the bit-depth, and it's the 4th bit (not the 5th) that specifies whether there is a CLUT or not. > Also, why are hex numbers shown as 0x01, 0x04, 0x09, etc. instead of just > 0x1, 0x4, 0x9 and for that matter, why use hex at all? No idea - it doesn't make any difference. I guess it sort of implies that you're looking at the individual bits of the number instead of the number itself? -- == James_Russell@scee.sony.co.uk ph: +44 (171) 447-1626 - fax: 390 4324 == Tools and Middleware Licensing Manager - Sony Computer Entertainment Europe At the border: "What's in the trunk?"
