Multi-session media which bear a xorriso image for overwriteables

in their first session would get a TOC of that first image rather

|

It is not possible to distinguish a BD-RE from a single session

BD-R with an image for overwriteables. But as soon as the media
|
|
|

bears 2 logical tracks it cannot be overwriteable.

So count the number of tracks first.
