My first pack of DVD-Rs cost me $40 for a 5-pack. Still, there's no other option for storing digital video to watch on your TV or to conveniently back up data that's larger than what fits on a CD -- a CD stores about 700MB, while a DVD stores 4.7GB, about 6.5 times more. So, with blank CDs costing about 30¢, that's almost $2 vs. the $8 it costs to store the same amount on a DVD.
But that has definitely changed. Read on for details on this pricing miracle.
Today I bought my first spindle of blank DVDs. A spindle is a bulk pack of blank media. Blank CDs or DVDs are sold in packs of 25, 50, or even 100, stored on a plastic container with a spindle in the middle which is threaded through the hole in the center of the discs.
I typically go to OEMExpress here in Ottawa to buy blank media, or any other component parts I might need. It's a little shop with nothing more than a counter and a giant warehouse, located on a side street that's hard to get to on foot.
For about a year, blank CDs have stood even at about 30¢ each. If you're paying more, you're paying too much -- I guarantee there's a store somewhere close by where you can get those kind of prices.
However, the blank DVD-Rs (there are a bunch of different formats, including DVD+R, DVD-RW, and DVD+RW...DVD-R still seem to be the cheapest and most common) today cost $79 for a 50 pack. Or around $1.80 each, which is all of sudden slightly cheaper than the equivalent amount of CDs!
Of course, DVDs are no good for making music CDs to play in the car, and not all computers have a DVD drive that can read them. But from now on, I'm going to do all my large archiving with DVDs.

9.5gb dvd video has very low
9.5gb dvd video has very low resolution. it's not clear on my 1080p tv.
some tidbits
I am tempted to by tape, at least it will last. A slow burn may not be a bad thing. Media without a good shelf life (20 yrs?) should be illegal :p Will they last longer than two years?

A few interesting assertions, otherwise just the usual handwaving.
"True DVD" is pressed (ie not feasible for personal creation) and can contain up to ~9.5 . I am pointing this out just so people know that a movie is most often greatly than 4.7GB .
I would like there to be a retail biz where you could go in with your VHS (/Beta) copies of movies and for a small fee, leave with you VHS copy and a DVD copy. Of course, the DVD copy could not have any "special features" not on the VHS, but otherwise it seems like "fair use" to me.
Linux software is not quite there with DVD burning. The burning software is there, but it is not integrated into how you want to use it, the good: data backup and music ripping software.
DVD videos that are 9.5GB
...are dual-layered.
you can tell by the golden tinge in the sheen of their read-side, which is from the inteference of the double metalizations. You'll also notice how some DVD players hickup when switching layers and refocusing, in the middle of the movie.
Burners which do dual-layers are in development.
about double layered DVDs
I never used double layered DVDs in my whole life but i do burn DVDs most of the days.
What I want to know is how double layered DVDs work and what are some of the basic differences associated with double layered DVDs.
all my computers read DVDs
but only one has a burner. that's the part that sucks.
as expected, I now use my notebook 85% of the time. really want a DVD burner on that but it only burns CD.
the other part that sucks is how long it takes to burn a DVD even with 4X burner.
I'll be getting an 8X dvd burner soon.
I like this page layout way better, BM. but what happened to the login and logout?
Design comments...
...here please.
I have a DVD drive for my PC, but it's currently sitting on my parts shelf. Yes, it seems to take forever to burn DVDs....I keep trying to tell myself it should be 6x longer than burning a single CD, but it still feels slower.
about DVDs and CDs
well bmann, when burning DVDs it seems to take a longer time mainly because the computer has to do a lot encoding for the video that you burn. for CDs you dont have to encode apart from the audio encoding. for DVDs you have to both video encoding and audio encoding.
I hope that answers you question.
if you still think this slower thats prolly you're biased towards CDs.
