Dual Layer Data Discs

[shoek]

Hi All,

First... thanks to L-UK for creating an excellent program!

I have a software product that is bundled with loads of content, so much so that the product ships on 3 dual layer DVD's. We use ImgBurn to build each of the 3 DVD+R DL (Verbatim) masters, and send those to the replication house for pressing.

 

We recently re-wrote the install to use Microsoft's MSI engine, and we're seeing some users who fail to install the product because MSI errors out when trying to read the file that spans the layers. Sometimes these users cannot even copy the file that spans the layers in Windows Explorer either.

 

Is there any setting in ImgBurn that could be used to make sure that no file starts on L0 and ends on L1? I realize the DL is usually reserved for DVD-Video projects where the files are so big this would be unrealistic, but in our case our file sizes are medium-large, and we'd sacrifice a little waste of space in order to ensure that a single file is not located on both layers.

 

One thing that is clear from this experience is that the quality of DVD drives for reading dual-layer discs is all over the map!

 

Thanks in advance,

For a data file, it matters not at all if it spans the LB. It is down to the quality of the burn (pressing in this case). If needs be, you can make an ISO with a file with null data to pad out layer 0. Test with ISOBuster to see that the LBAs match.
