using readcd, i found that the images burned to the drive were the right size:
-rw-r--r-- 1 radu radu 3709665280 Dec 16 03:03 sol-nv-b77-x86-dvd.iso (the original image)
-rw-r--r-- 1 radu radu 3709665280 Dec 16 03:21 sol-nv-b77-x86-dvd.iso.2 (the DVD dump from readcd)
-rw-r--r-- 1 radu radu 3709665280 Dec 16 03:24 sol-nv-b77-x86-dvd.iso.3 (another readcd dump from another DVD coasted by cdrecord)
however, they had extra bytes prepended:
% head -1 sol-nv-b77-x86-dvd.iso
CD001Solaris SOL_11_X86 f@@^"¨¨k
% head -1 sol-nv-b77-x86-dvd.iso.2
*# # *CD001Solaris SOL_11_X86 f@@^"¨¨k
The ends are all 0'd out, so I can't tell a difference there, but it appears like the 6 bytes at the beginning are to blame. The image has the right size, so I'm assuming six bytes are skipped at the end, but I don't have time to check now.
I had the same issue trying to burn an ISO image to DVD-R.
growisofs and cdrecord both failed to produce a proper DVD
cdrtools (10:2.01. 01a33-0ubuntu2)
dvd+rw-tools (7.0-7)
cdrskin worked perfectly however.
