Sorry if you feel I wasted your time. I did read the change log for ver. 2.1.0.0 again and again but could not find any mention of a fix that seemed directly related to my problem. I wasn't sure if it was media related or program related, therefore not sure if upgrading would solve it. That is why I thought I'd ask. If I did miss the relevant entry in the log, perhaps you would be so kind to point out to me. Thanks.

Point taken. Actually that DVD played fine. It's sometimes hard to keep up with new releases of all the progs on the computer. Same with new firmware, drivers.

I 00:48:12 Shutting down SPTI... I 00:48:12 ImgBurn closed! Is there a safe file size limit to write for DL DVD?

Is manual verification after burning is completed possible without the iso (the files were burned directly to DVD)?

TBH it doesn't bother me: using Arcam DV88 to play it's not a major issue. I suppose some DVDs I watch (concerts etc) is split into sections anyway so the layer break may well occur between sections.

Got it, thanks!

In the Create Layer Break Position window, Very Good star is a blue colour. But when one LBA set is highlighted, whatever star next to it changes to blue. Although not identical to the blue of Very Good, it's somewhat confusing at times, esp. for the green and what stars before highlighting. So, can the Very Good star be assigned another colour?

I think he might find this confusing: Write Mode only lets you choose image files to burn. To burn files directly from the HD, you have to go to Build Mode and choose DVD-ROM drive as Destination.

Many thanks for taking the trouble to explain the above. The verification plot has a gradient (the speed increases) in the good burn graph, does that mean something in particular? So this is the tool I need to install to display the graph? http://www.dvdinfopro.com/ At the bottom of the graphs, I see: Download ImgBurn Run Imgburn, so there's some connection between DVDInfo and ImgBurn?

I see lots of DVDInfo graphs in the Media section. The DVDInfo and DVDInfoPro (by Nic Wilson) I search on Google look different. Is it another tool built-in or plug-in in ImgBurn? And is there a guide somewhere on how to interpret the graphs? What is a good burn supposed to look like? Thanks

Burn failure may well not be related to re-encoding. Save the files to HD and test them first.

Thanks again. I've always assumed that is all hardware (DVD player) related.

Mode > Write Source > select nrg But if you want to burn a standard DVD, make sure you author it properly. Nrg is Nero image file.

Sorry if it seems obvious, is this the presence or absence of slight pause when switching layers during play, or something else?

I see. I haven't watched a superbit DVD. How do I know if my player support seamless layer break?
