no luck with dvdauthorgui either. using 3 VOBs created fromt eh same music DVD but getting error messages like "invalid frame rate", and apect ratio warnings even though these were created with FAb's vob passthru so frame rates should be unchanged - see below for sample.
I've concluded that a better method is to go back & start over using the combination of Fab & Shrink cusomtise options( for specific title/chapter selection ripsfromt he DVd that I want to combine) and then
dvdfab's merge option for rec-ombining as described elsewhere.

There was an error in the authoring process. It appears that something is wrong with the muliplexed VOB files.
