After 3-4 hours of rendering the system stops and gives an error message .. adding assets to DB.
I've defragged the drives . nothing.
I have been using the same process and codec with edius 5.12 for months now and successfully using dvdit prohd - but suddenly it started producing this error. Only on hd files. I can import the same hd file and render a SD disk with no problem - only occurs when trying to output BD disks.

Any Ideas anyone?

thanks
Steve

are you exporting elementary streams from Edius 5.12? if so, they should be accepted as they are and compilation will be over and done with in a few minutes

We do have the same serious problem while compiling to disc. The error occurs just while "adding assets to DB" and it depends on the combination of video and audio tracks it seems.

If we create a new project, add one video (avc) plus three audio tracks (ac3) and compile without any menu it works. But if we add the same files to a project with existing menus it will put out the error while compiling. Strangely if we remove all audio tracks it works. We tried this with different files and sizes (M2V, PCM etc) but it's always the same problem.

Since the error is not specified in any way it's nearly impossible to check out the source of the error. Currently the software is not useable for creating BD Master files, sadly. There are no updates available (since version 6.4), so we are locked and forced to use other software in the future.
