Re: Self-written DVD+Rs that cannot be read...

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.) Not necessarily.  More expensive does not always equal better for CD or DVD blanks. Did you answer my previous question about whether the drive supports DVD+R and DVD-R, or just one of the two? Hugo
