154 track limit?

[Barry Kauler <void@dodo.com.au>]

I read somewhere that DVDs have a limit of 154 tracks.

Could someone kindly advise me:
when you use "growisofs -M", it creates an "incremental track"
on the DVD -- is this a "real" track?

In other words, do these incremental tracks/sessions count
toward that 154-track limit?
