[QUOTE=mcodeg;2603746]So if I had changed the default output value to dvd9 (which I probably did) and backed up dvd5 discs I wasted alot of dual layer discs but wasn’t asked by Imgburn for a layer break before. With an update that defaulted back to dvd 5 imgburn properly asked for the break when i backed up the dual layer disc?[/QUOTE]
NO that’s not correct.
Only if you did the rip with output set DVD9 will you be ask for a layer break.
You cannot back that DVD9 rip to a DVD5 disc without compressing it.
You can however burn a DVD5 rip to a DL DVD disc but it shouldn’t ask for a layerbreak because the DVD5 rip should all fit on one layer. I don’t know this for sure it might ask but there wouldn’t be a need to.
