In my case, I was writing (well, updating anyway) an app that required a
DVD-R/RW disc, so I had to program in checks to make sure the user didn't
try to put a different type of disc in before the app started writing data
to it. I went the SPTI/ASPI approach for that.

Yes if you need to ID the disc type you have no choice.

Do you use Get Configuration/Profile number?
I think it's an ideal way to do it.
If your profile numbers are up-to-date per MMC 6/MtFuji 7,
it'll ID any possible disc type the user could put into a drive.

There's also an ioctl get config named
IOCTL_CDROM_GET_CONFIGURATION
(in DDK/ntddcdrm.h & ntddmmc.h). The ioctl is FILE_READ_ACCESS
and you only need GENERIC_READ, FILE_SHARE_READ for the
DevIO handle. So you would be able to avoid the SPTI/Admin Privs issue.

I have tested it on my XP/SP2 system and it works in the user account
just fine. The catch is I'm not sure if it is supported in Win 2K or Vista.
I've read posts in the MS NGs saying at least some of the multi-media stuff
in those headers was no longer supported. Maybe one of the resident gurus
on this NG knows.

On the other hand, all the CD/DVD recording software I'm familiar with
uses the SPTI to send their scsi commands so it can't be too much of an
issure. It's what I use.

I'm not aware of such solutions. I'm interested but you
leave me with too little to go on.

Can you please be more specific.
At least tell us what news group(s) ...
and maybe a little hint about what these solutions involve ?

Profile numbers, yes.
