I just bought some Dual layer DVD's, as they seem to be getting more affordable. But In creator Classic 7.5. I am not able to burn 8.11 gb of data on a dual layer; I need to remove around 190mb in order for it to fit.  It is saying I require another DVD. yet I can easily burn that same data on 2  regular DVD's. I am confused about the 7.9 gb that is on the properties of that dual layer. I thought you had 8.5 gig of space on a Dual?  If anyone can give some insight on this, I sure would appreciate it.

Rayi,

You need to know that a double-layer DVD holds less than twice the capacity of a single-layer disc.

A single-layer DVD holds around 4,700,000,000 bytes
A double-layer DVD will hold around 8,500,000,000 bytes (less than double the above capacity)

Creator Classic 7.5 calls those capacities 4.7 GB and 8.5 GB, (calling 1,000,000,000 bytes a GB).

-=-=-=-=-=-=-
Note: The original binary gigabyte was 1024x x1024 x 1024 bytes, or 1,073,741,824 bytes and not 1 million bytes. Many people still use the old value, and when that is used those disc capacities become 4.38 and 7.92 GB.

This can be terribly confusing, and if you're trying to calculate what will fit on a disc you need to know how big the KB, MB, and GBs are that you're trying to work with.

Careful people are now using the notation 'GiB' (gibibyte) for this original larger number, but both standards are still in use and are often interchanged. You may well find that Windows calls your "200 GB" hard drive 186 GBs. This is because it holds about 200,000,000,000 bytes, or 186 GiB.

Thanks for your response. I guess all we need to know is that you really only have 7.96 gb of free space in terms of Windows. For some reason, I didn't think about that with regular DVD's before and they are only 4.38 gb and not 4.7. I find that the more I get in DVD media, the less I like it. I will be glad to move towards something better. I have found it to be unreliable.

Just curious: unreliable in what sense?

[Rayi]

For example, I had converted all my home movies into DVD's but sometimes they freeze or don't play in my expensive newer Sony DVD player; yet they play fine in my mother's JVC less expensive DVD player. I used DVD+ and verbaitim DVD's. Very frustratring how they vary among different DVD players.

I feel that Sony's seem to prefer 'dash' media.

My Sony Recorder will not play 'plus' DL media but my Sony Player will play the same disc…

One thing I have not tried since I first tested 'plus' DL on it was setting the Book Type to DVD-ROM. This is something that the Burner has to be able to do at the time of burn.

With 'dash' media it is always set that way during manufacture.

I will try to run a 'plus' DL that way and see if it improves its' compatibility.

There are three different DVD recordable formats DVD-R RW, DVD+R RW and DVD-RAM. Booktype field identifies the disc as either a DVD-ROM, DVD+R(W) or a DVD-R(W) disc and is for a big part responsible for the compatibility. Because this setting is overwritten during the DVD-R production process it can’t be modified afterwards, the laser of your DVD recorder simply can’t write to that part of the disc.  
So after burning a DVD-R, DVD+R, and a DVD+R Booktype changed to DVD-ROM. A disc identifier tool ( DVDinfoPro, Disc Identifer, CDDVDSpeed). The -R Disc & Booktype will be -R, the +R Disc & Booktype will be +R, and the +R Booktype changed to DVD-ROM, will read, Disc +R & Booktype DVD-ROM.

Compatability can be a problem, but what's the alternative?    It's a great way to share home movies with friends.

You might try burning to an 'image file' first (DVD Builder Advanced Settings) and then use Disk Copier to burn the 'image file' (.iso)  to a DVD.    It makes making multiple copies easier and by separating the encoding and burning process, you increase the odds of you getting a good 'burn'.

( And unlike James' experience, one of my friend's has a Sony Player that prefers +R media. )

My Sony DVP NS70H, a year old. Will play DVD - R, + R, and  + R DL Booktype set to DVD-Rom with no layer break problem.

Yup.  My friend has another Sony DVD player that will play all types of DVDs.

It's more of a DVD player problem than a DVD problem since the DVDs will play on a computer.

[Rayi]

I did later decide to redo them from .iso's but still had the problem for some reason. My daughters Panasonic DVD player also played them with no problem. Just this Sony DVP NS715P. I wish it would just quit working altogether. But, yea, I realize that there are no alternatives but none the less, I am hoping for something more reliable eventually. Perhaps that will never happen. Also, I thought, from an earlier thread  that the "+" format was suppose to be more compatible with Sony's DVD players. Dash formats seem have more problems.

[Brendon]

I think you are just unfortunate enough to have a dodgy Sony, Rayi.
Personally, I don't trust them at all after the 'rootkit saga'.

And fwiw, the plus format seems to me to be technically better than the dash one (and much more up to the minute).

I have a Sony DVP NS715P and I have not had any problem playing any kind of DVD whether +/- or +/-RW. If it played on my computer it also played on the stand-alone DVD player.

Well, in that case, since Walt has the same player and is having no problems......

Have you checked to see if there are any updates for your DVD burner from the manufacturer?

[Rayi]

I guess there must be something wrong with this Sony DVP NS715P standalone player. Maybe it needs cleaned.

[james_hardin]

Doubtful that it will make any difference… There are different firmware levels for Players just like Burners. Depending on when it was made, the firmware applied was current for that time.

Player compatibility issues started when the first burner/media hit the market. Things have gotten better but I really doubt we will ever have 100% compatibility.

Look at CDs! After 10+ years of Music CD burning there are still those having trouble getting a Music CD to play!

DVD's will not reach 100% and BlueRay will muddy the waters even more.

I just tried a DVD+R DL set to DVD-ROM and it still will not play in my Sony RDR-GX7 Recorder/Player.

You may want to hang on to the 'problem' discs and next time you are shopping for a Player, take them along with you.

[Rayi]

Also, regarding Dual layer DVD's, when I am doing a data DVD, it gives me a warning to finish the session; it says it may not be compatible in another DVD player and it may even damage it. I hate to heed this warning because I want to do later sessions. I wonder if anyone has had any experience with moving data DVD's do other DVD players on other computers. (PS. I added this message before and it didn't take before. I hope it is not repetitive.)

Rayi.
Are these -R DL or +R DL?

cdanteek

[james_hardin]

That would be, this warning?

I get that with the 'plus' DL media. (neither of my writers will write Session to 'dash' DL media)

Both of my burners can read it but the DVD-ROM's in my other PC's cannot. No surprise there, they can't read DVD RW's either!

As long as you will have a DVD Burner or access to one, there should be no problem accessing the media.

I am using verbatim DVD+R DL. Now the DVD rom that I was using it in at work has no problem reading this DVD+R DL but I did finalize it.
