Type to store per-command data.

The following structures are used in both the VMGI and VTSI. DVD Time Information.

The following structures relate to the Video Manager. Video Manager Information Management Table.

(Incomplete)

Structures relating to the Video Title Set (VTS). Video Title Set Information Management Table.

For btngrX_dsp_ty the bits have the following meaning: 000b: normal 4/3 only buttons XX1b: wide (16/9) buttons X1Xb: letterbox buttons 1XXb: pan&scan buttons

They are all represented by 4 bit number and stored like this [Ci3, Ci2, Ci1, Ci0, A3, A2, A1, A0]. The actual palette that the indexes reference is in the PGC. split the uint32_t into a struct

NOTE: I've had to change the structure from the disk layout to get the packing to work with Sun's Forte C compiler. The 4 and 7 bytes are 'rotated' was: ABC DEF GHIJ is: ABCG DEFH IJ
