Rivergate Software Inc. - makers of DVDAfterEdit

Our support forums and support emails have encountered some Eclipse and Pre-Mastering errors that have been intermittent and difficult to pin down. Foremost among these is the Eclipse error "VOBU length and number of sectors disagree". Blame has been pointed at I/O errors with either SCSI DLT or DVD-R, but our research indicates that it is more likely an authoring error.

We have added a function of HDAfterEdit which checks all Nav Packs in a DVD or HD DVD. The user interface not yet in its final form, but we will make a download available to anyone encountering this error during attempted replication, and will include a more complete implementation in our next formal release. This function is the beginning of more extensive verification that we will be adding to HDAE as time goes on.

Even if it is an authoring error, the VOBU length error could be introduced during output of a DLT or DVD-R from the authoring program. So if someone has a DDP image (or one copied from a DLT), it can be easily checked by extracting the VIDEO_TS folder with DVDAfterEdit and then opening it in HDAfterEdit, or by opening the image directly. If a VIDEO_TS folder was output from the authoring program, that can be checked also, of course.

Please make all inquiries and report your results on our forums, so that the information can be shared by all.
