Is this a PDVD error code? When does it pop up? And what version of DVDFab did you use to make the Blu-ray folder and what is the movie title?
I am currently watching Battle: Los Angeles on PDVD-Ultra v10.0.1705.51 playing from a BDMV folder via miniso and DVDFab Virtual Drive. PowerDVD wrongly said it needed an update to play this content, but plays it fine if you click Play a second time. I am not sure which version of Virtual Drive I'm using, I'll have to check it and edit it into the post.
//EDIT// Works fine with DVDFab Virtual Drive v 1.2.0.1 and 1.3.0.0 for me, not sure what you are seeing. Perhaps there is something wrong with the folder structure or content. ??
