IFO/BUP 32K Padding

Recommended Posts

What is IFO/BUP 32K Padding and what exactly does it do when enabled?  Other than, obviously, padding IFO/BUP files to 32 K size if they are less than 32 K.  :D  Thanks!

It ensures the IFO and BUP aren't in the same ECC block (16 sectors = 32KiB) on the disc. That way there's less chance of them both being unreadable if the area gets damaged.

This addresses something I just thought of yesterday!  :o

 

 

I was contemplating the use of BUP files as part of the DVD Video standard.  My thinking is if a disc is damaged where IFO files are stored and can't be read, then the damage would most likely prevent its BUP file from being read because the IFO and BUP would probably be stored in the same area on the disc.

 

 

Of course, most damage to a disc means that part of a VOB can't be read, so it makes playing the IFO or BUP redundant.  :wink:
