DVD-R do not fit on another DVD-R...Strange

[bacardi/avt]

I have a very strange problem.

I have burned a DVD-R from an Iso I made worked like it should. I think the media was Ritek g04 and the burner a Sony 500AX. This was a few moths ago. Now I have got a new burner and new media (Plextor 716, Verbatim 8x, TY02) but when I tried to copy the DVD-R all my programs told me that the destination media was to small, very strange. So I went to check my original DVD-R in my player and it works like it should.

Finally I ripped it to HDD and used Vobblanker to gett rid of a small intro menu that gave me 7MB smaller Iso and then I could burn it.

My question is: Do anyone know what could have happened to the original DVD-R or has the size on blank media shrunk

Sounds like you simply burned the original a little larger than most programs are set for their 'max' burn size. For example, I think DVD Shrink defaults to about 4470mb in size, but in reality a DVD holds about 4483mb. You can change the output to another size though. Similar size restrictions are available in Nero and other programs as well.

You might be right, I did not think of that.

Still when I checked the original DVD-R it said that it was 4464MB and since I took out 7MB it ended up at 4457MB, But shouldn't the original fit anyway? I actually tried Plextools, Recordnow and Nero and got the same error, could it be a limitation in the firmware of the new drive prehaps?

Have you checked in the options of those programs what the size limit is set at for DVDs? You can always change it, I think I have Nero set to 4482mb.

[bacardi/avt]

I just checked Nero and it was set to 4483MB...so it should have worked...anyway the reduction I made (7MB) of the original DVD-R allowed me to burn it with my new drive and media, so it's no panic...

I was just curios what caused this....

Two ideas:

There are instances when an ISO can bloat itself. I've not really run into this yet. Just read about it.

Certain programs, in the early days (2000-2001), would sometimes allow overburn. Not by much, but enough to cause duplication problems.

I doubt either is the case. Maybe the ISO bloat, at most.

Maybe you're witnessing the capacity difference between the - & + formats?

DVD-R = 4488MB
DVD+R = 4482MB

??

[bacardi/avt]

Nope

They are both DVD-R

one Ritek G04 and one TY02
