I have been struggling with this one for couple of days now.
It appears that my Windows XP think that my Pioneer DVR 110 D is a CD-ROM drive. I've learned how to make windows think it is a burner, but I can't make it recognize it as DVD/RW drive. I had daemon tools installed + alcohol 120% + powerISO. I've uninstalled daemon tools and disabled all the virtual drives to no avail. It's still a CD-ROM. Some functions are gone (like auto-play DVD movies). When I check the volume properties and click "populate" button (while DVD movie inserted) all the values are the same as if the drive is empty.
The drive reads and burns like before, but with the windows thinking it's a CD-ROM, some of the perks of a DVD/RW are gone.
I've tried uninstalling the driver via device manager, reinstalling the chipset drivers, manually installing the CD driver... next step will be flushing the device info from the registry, but I'm hesitating...
Reinstalling windows is out of the question. It is up-to-date now and reinstalling it would mean downloading all of the updates again via modem. No way.
For the record:
Nero works with it like it worked before it became CD-ROM.
I can't play DVD movies in media player 10. Says "Windows Media Player cannot play the DVD because a problem occurred with digital copyright protection."
PowerDVD says "Copy protection cannot be enabled. Please make sure any other copy protected content is not being shown now."
Intervideo WinDVD plays the movies.
There is no "DVD movies" listed in the "Autoplay" tab.
