"Failure to rearrange DVD-Video"

That is what Nero (5.5.9.0) insists on informing me whenever I try to re-introduce a rebuilt (Maestro) movie back into the main project.... and I can`t find any information on what it means .

On the plus side I`m having no troubles re-encoding and then linking everything back together (thanks to IFOUpdate). And the resulting project is fully working through PowerDVD (chapters, scene select, menus etc).

The only way I have to get around the problem appears to be to copy over the _0.VOB and _0.IFO from the Maestro project and hence lose the menu and or chapters but then Nero is happy again!

Please any ideas anyone???
