So my rounding of using 4700000000 bytes is not so wrong after all, I haven't had problems with it. ;-)
If the size you use is about that, no it's not that far out.
I should modify it to 4699998208 or 4700000256, the closest 2048 multiples.
You'll want it a multiple of 32768 due to the fact that the sectors are usually written[0] in blocks of 16[1], so you'll want either 4699979776 or 4700012544.
No problem, I suppose. It might make dd a bit faster. As long as it is smaller than the maximum size of a dvd, with a little margin.
[0] and, since read-ahead is employed, probably read as well.
[1] Executing 'builtin_dd if=blank.image.iso of=/dev/dvd obs=32k seek=0' ^^^^^^^ as seen in this output from growisofs.
Interesting. Maybe some time I'm bored I'll time dd with several block sizes. :-) - -- Cheers, Carlos E.
