Not entirely. -pad for _audio_ tracks adds 0's to get a full last 2352-byte block (which is required by standards). -pad for _data_ tracks always adds 30kB of 0's to make it compatible with buggy early 2.0 (IIRC) Linuxes and some other *UXes. Data tracks are always 2048-multiples, and if not then that's a serious bug in mkisofs (or equiv). Regards, Anne Bezemer
