Uhh, the whole point of the XCD format is that, as the movie formats used already have some ECC capability (apparently), they dispense with the per-sector CRC check. Instead of writing 2048-bytes per sector with CRC, they write 2352 bytes per sector with no CRC (in exactly the same way as CDDA Orange Book data is written - aka regular audio CD). The first track on the CD image is actually used to hold backups of critical parts of the file format or something. Anyway, this means that you can fit >800MB on regular 80min CDR/CDRW media (which are advertised/labelled as 700MB, because that's how much they hold of 2048-byte-per-sector data). Cheers, AS
