Looks like the file dvd8_2.iso is truncated.
The Primary Volume Descriptor (superblock) says the ISO has
2284052 * 2048 = 4,677,738,496 bytes, whereas libburn sees
a pseudo-drive of 1941504 * 2048 = 3,976,200,192 bytes.
It gets this size info from system function stat(2).

Check independently of xorriso by

 ls -l /media/richard/Lexar/dvd8_2.iso
 /sbin/isosize /media/richard/Lexar/dvd8_2.iso

Ask xorriso for more info by

 xorriso -indev /media/richard/Lexar/dvd8_2.iso -toc  

2284052 blocks is a plausible size for a DVD image. Max size
for DVD+RW is 2295104 blocks. So probably the file lost 700 MB
during some transfer.


Have a nice day :)
