Windows 7: The use of C/D's or DVD's

Is their things ISO, memory test ect. backup or anything that you can burn to a CD that you can't burn to a DVD? The reason I ask is when reading some post here and I don't remember which one the OP was told that it couldn't be burned to a DVD had to be burnt to a CD.

not as far as i know - an optical disc is an optical disc.

of course, there's stuff that would fit on a dvd that wouldn't squeeze onto a cd, but not the other way around.

also of course, cd's are cheaper, so it's best to use 'em if you got 'em.

third of course, you can't stick music onto a dvd and expect it work on a cd player.

As far as I'm aware, creating a disc for data recovery or diagnostic purposes is best done using a CD rather than a DVD.

As for why this should be so is something I hope one of our experts can shed some light on.

And, as Mickey rightly points out, it's cheaper to use a CD whenever you can.

Like already mentioned, the only time I would use a CD over a DVD is for use in my car stereo or boot disks that are just a too small to waste a whole DVD on

yes cd's are cheaper but on the other hand creating the aforementioned diagnostic/recovery disc might be better done using a dvd. Dvd readers employ far more complex error correction algorythms and also dvd's as far as i know are much better protected against weathering, whereas cd's can be very easely compromised by even a small scratch on the label side or by moist environment... I myself use dvd's but each to his own Pointless to say of course, no wasting dual layer dvd's for this purpose.

Am I the only one that lives somewhere where DVDs cost less than CDs?

I don't think it makes a huge difference, but I usually go for the one that costs less, although I inspect them when using them when it's for important stuff in case there would be some scratch or something on it. Most of the time I go with the size of the file to be burned.

I think it pretty much comes down to what it will be used for, preference, and if it will fit on the CD or DVD when burned to either one.

If you buy packs at brick & mortar stores then DVD may be cheaper but spindles from online stores I think CD is still cheaper per disc. I don't know about the boot speed issue. Seems like DVD would have a higher transfer rate. Error correction would seem to favor DVD. Then again, not much use for CD these days except for the car stereo. Might as well use 'em for something.

Imgburn will burn an iso to CD or DVD provided there's enough disc space.

Thank you all for your post and inputs. I'm learning and I like that.
