Thanks, not the case though. I know people had problems in WindowsXP
with the DVDs I wrote, as well as checking the files myself - I run into
bad files as soon as 1/3 into the DVD. (Assuming files were added in
sorted order.) dd can fail quite soon as well.
BTW, I've noticed dd dumps being smaller than the original .iso - but
still all the files are fine (mount and diff -r gives "perfect
verification"). This being on CDs. I've not yet successfully verified
any DVD. 7 out of 7 checked were bad, and I handed out another 8 which I
therefore assume are possibly all bad.
I think I will try Verbatim's DVD-R (might that help?), then possibly
another brand, then I'll be looking for another DVD writer. (I have a
"BTC" writer - cheap cheap. Suppose I might paying for my stinginess
now.)
