Hi Ross,
Your reply is somewhat confusing, your saying that you bought a spindle of
DVD -/+ blanks and have been able to format them ?
My experience in having burned over a 1,000 DVD's under XP and Vista
is you don't need or want any kind of formatting if you're making a
traditional DVD, such as one containing videos, a slideshow, a
collection of Mp3 songs, stuff like that. The "formatting" is done
automatically during the "burn" process. The only time preburn
formatting MAY be necessary is for some types of drag and drop file
copying.
DV-RWs can be written over, it isn't reformatting in the true sense of
the word as it is normally used for computer releated topics.
Every spindle I ever bought regardless of brand, regardless of type,
R-, R+, RW-, RW+ always has one or two "bad" blank discs in it. Having
done this for years, ever since there was such a thing as a home brew
DVD and before that burnable CD's there always was at least one,
ususally 2 or 3 bad discs in a spindle. I don't like it, in fact I
HATE that, but that's simply how it is.
You know what I find highly suspect? Never in the same time period
when in a pinch I ran out and bought a few blank CDs or DVDs that come
in jewel cases have I ever got a bad blank media, always with the
spindles. Very curious.
