First of all note that 5.17 is strongly recommended update for those who deploy 5.14 through 5.16. It addresses problems with DVD-dash recordings performed with -dvd-compat option, i.e. very kind of recordings you're referring to. I apologize for inconvenience, but do upgrade.
Now to wrap up directly. DVD-R media recorded in Optorite DD0203 unit with -dvd-video option with growisofs 5.16. This media can not be accessed in Optorite (SANYO derivate) nor HP dvd300n (NEC derivative), but is accessible in HP dvd100j (Ricoh derivative) and some other legacy DVD-ROM/-Video units. Wow! If Optorite fails to read own media, while legacy units can, Optorite is the culprit. I can only suggest to lower the recording speed with -speed=1 and if it doesn't help, switch to another media brand. > I did notice from the units that will acknowledge the media; the > older units identify the "mounted media" as 10h DVD-ROM and the > Optorite as 11h, DVD-R sequential.

In vast majority of cases non-verbose dvd+rw-mediainfo output is more than sufficient. Let's say that verbose outputs should be provided upon explicit demand only. A.
