The "CD" in libcdio refers to Compact Disc's. DVDs are generally different animal. Perhaps there's another library out there that you might use for DVDs. libdvdread? I don't know.

However in 0.70 there is an interface to SCSI MMC commands, so if MMC is supported for the driver on your OS, you may be able to use the appropriate MMC command to get what you want.

libcdio still doesn't make a difference between a normal data DVD and a video DVD.

It seems that what you've added is a way to detect the actual, physical media type in the drive. What I was looking for was a way to detect whether the disc in the drive was a video DVD, or not. The medium being a DVD-RAM, or DVD+RW doesn't make it a video DVD.

A change was made to libcdio in CVS for GNU/Linux.
A new routine get_disc_mode was added to report the kind of CD e.g CD-DA, CD-XA mode{1,2} form{1,2} CD-MIXED, DVD-ROM, DVD-RAM, DVD-R, DVD+R and so on.

cd-info now gives this info.

Slowly this will make it into other OSs hopefully be complete for the 0.70 release.

However the API is in flux as it is determined what the proper level of detail should be or whether it can be implemented universally.

libcdio doesn't recognise video DVDs as different, it thinks that video DVDs are just normal CDs with an iso9660 filesystem.

$ cd-info
[...]
CD Analysis Report
CD-ROM with ISO 9660 filesystem
[...]

libcdio, and cd-info, should be able to recognise that it's a video DVD.
