Risk in Burning DVD with > 100% Capacity?

rtbond wrote on 6/4/2003, 10:07 AM

Hello,

I've used the DVDA Optimize DVD option to adjust the encoding rate such that the estimated size of the DVD is 102% of the 4.7 billions of bytes capacity of my DVD+R/RW disc. I then select Prepare DVD (as DVDA does not yet support the Dell/NEC ND-1000A DVD+R/RW drive!), and use Nero to actually burn the disc.

Nero complains about a file allocation error (this seems to always happen with DVDA authored discs and Nero, even if DVD project is below 100% of disc capacity). I ignore the Nero warning and burn the disc. Everything appears to work fine, and the disc plays in the various DVD video players arond the house. :)

Is there any risk in bumping up the encoding rate so that the DVD+R/RW disc is this close to actual capacity? Note the Nero burn windows actually indicates the DVD project file total capacity is at or slightly above the DVD+R/RW disc capacity (generally consistent with what the DVDA Optimize DVD screen was telling me).

Thanks!

The size shown by the "optimize" command is only an estimate. After you prepare the DVD, you might want to check on the actual size of the output directory structure.

The only problem with checking the size after you prepare the structure is that you may have to redo the 'prepare DVD' if Nero says it cannot burn it because it exceeds the 4.7Gig capacity.

If DVD-A is saying your project is at 102% what makes you think you can burn it with Nero or for that matter any application? You can't get more than 4.7GB on a DVD and even trying to get a full 4.7 is probably foolish because it is an estimate. I NEVER go higher than 4.6 and that gets very, very close to maxing the DVD out.

Just curious, why are use burning with Nero after you started with DVD-A?

As I mentioned in my original post, DVDA does not yet support the Dell/NEC ND-1000A DVD+R/RW drive. I find this rather stange, as Dell ships a lot of these drives, so you'd think SoFo would have DVDA directly support this writer.

I noticed the Nero was consistently showing my DVD project as being smaller than DVDA was **estimating** it was going to be. As a consequence I decided to try preparing a DVD in DVDA that was slightly larger than DVDA estimates would fit on type DVD-A disc. It seems to work OK (at least for this particular project).

I just wondered what others had experienced using DVDA regarding performing the DVD Optimization/encoding rate. (i.e., just how closed to the edge (i.e., 100% capacity) do you push things in DVDA)

I wouldn't go beyond 98.5 99% tops

How do you Durn it in Nero? - My nero only offers vcd & svcd it's build 5.5.9.13

You have to buy a $24 Nero MPEG-2 plug-in to burn to DVD

The lastest Nero version is 5.5.10.35 (which you can download from their site). I'm not sure when Nero added DVD support, as I'm a new user. If you are using the Nero Express program, you need to be sure you select your DVD RW/R writer from the opening screen. If your CD-RW/R drive is selected, then you will not see the DVD-Video options.

The Nero MPEG encoder plugin is only required if you are going to encode MPEG-2 using the (lame) NeroVision package that is bundled with Nero-ROM. No encoder functionality is need to burn a DVD using files encoded outside of Nero.

I've been authoring in DVDA, preparing the DVD to hard disk, and then using the Nero DVD-Video cretation capacilities to burn the DVD disc using the files created by DVDA.
