understanding iso-info -l output |

Hi there,
I'm trying to associate a list of file accesses by file offsets within
an .ISO file. I need to lookup paths/filenames based on the file offset.
The file I have is 532963328 bytes long, which would be (260326)
2048-byte sectors.
When I use "iso-info -l", I'm only seeing outputs from LSN's 178 to
178993. It seems I'm almost missing around 80k sectors.
The extra space is not padding, and the OS is definitely accessing parts
of that CDROM. I have many accesses in the 506,994,688 to 518,455,296 range.
If I simply multiply the LSN by 2048, should that be the file offset
within the .iso?
I think I'm missing something fundamental here, so I appreciate the help.
Thanks,
Keith
