Hi, does anybody know the best place to buy these discs?.Most places i've tried only have 2 speed.
Verbatim 4x speed discs can be picked up cheapily from:
CD-R Media also does a variety of 4x DVD-RW media:
...including Verbatim and TDK.
Ensure your DVD recorder/DVD burner can take 4x DVD-Media before using it!
i dont get that - i've never had any trouble with any DVDR's i've put in mine (whatever was the cheapest at the time) - but i've always assumed:
disc write speed (x4, x8, whatever) is the 'guaranteed', 'maximum' (upto)speed you can write on it
higher-write-speed discs = higher grade film = more receptive = backward compatable with any lower speed writers
i.e you could put a x million disc in x 1 writer - but if you put x 1 disc in a x 2 writer you can expect trouble, because the disc is not guaranteed to be receptive at that speed
saying that, i've written @ x12+ to x4 discs, and although i fully expected to chuck half of them away, they worked OK
is that not so? - or more specifically, has anyone, ever had a problem using high-speed disc in a low speed writer? (that's the bit i dont get - and that's when i'd definately send the discs back)
JethroUK, I assume you are using DVD+ media though? DVD-RW has compatibility problems between v1.1 and v1.2 media types. One of the reasons why DVD+RW is more popular than it's minus competitor for PC use. DVD-RAM and DVD+RW do not have problems yet - although they will have at faster speeds.
I'm with Rasczak on this one. It's worth checking your manual about the disc versions to use. Each machine will vary and, for the sake of a quick check, why not buy the sort that are guaranteed to work well? Also, some machines will use a wider variety of media that they state in the manual but then you find that some of the functionality is lost when not using the "stated" media types.
SVP are a great supplier and Verbatim MCC code DVD-RW 4x discs are a very good quality choice.
It does, the new 8 speed version media will not record in any existing hardware.
As for DVD-RAM, Raszcak will say (no guarantee) that all faster DVD-RAM media will be backwards compatible, but then so did the +RW Alliance before 8 speed +RW came about, only to break that promise later, so there are no guarantees. The same issues will be apparant on Blu-Ray and HD-DVD as re-writable speeds increase.
The facts: Phase change material used on DVD-RW/+RW, DVD-RAM, and CD-RW, can not be made to cover a broad range of writing speeds in the way write-once dyes can hence the breaks in writing compatibility for faster media. Its the way the technology works.
This isn't a DVD-RW v DVD+RW v DVD-RAM argument Philip so you can climb down from actions stations for defence of -RW!
And 8x +RW media isn't available yet - thus in the future is quite a good description of when the problem will occur. And notice I did use the word "will" in my post!
I said so far DVD-RAM doesn't have a backwards compatibility issue - indeed AFAIK the proposed specs for 16x DVD-RAM will be incompatible - but then nobody is seriously considering 16x DVD-RAM because there is no market for such discs. By the time they arrive they will be completely over-shadowed by HD-DVD/BluRay - so nobody will really care.
But as things stand now there is an issue with compatibility of 4x DVD-RW media which needs to be mentioned. If/when/as it becomes an issue for other formats then that too will be mentioned!
The specs are finalised and it has already been made known that 8 speed +RW media will not be backwards compatible for recording. You just said in the future, I offered a more complete picture of that future that you left out.
Then please do not turn it into one then.
Yup, a vote from me on the Verbatim's and blankdiscshop.
