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.
