Its the OEM version of a Samsun SH-223.
I believe ImgBurn will automatically burn a +R disk as a DVD-Rom using a Samsung burner so you may already have burned them as DVDRom. Put one of the burned disks in the drive and start ImgBurn. On the right side of the window in ImgBurn you will see a lot of info on the drive and the burned disk…go all the way down to Physical Format Information (Last Recorded): The next line will show the disk ID code, then the next line will be Book Type: The book type on the disk should read DVD-ROM.
If it doesn’t say DVD-ROM here, if it says DVD +R, you may have to change the setting manually. Look in Tools–>Drive–>Change Book Type and set it manually to make a DVD+R into a DVDRom as you burn.
The media you are using isn’t the best, and that drive isn’t the best Samsung either. You can try a different media, like Verbatim and that would certainly be an improvement, but it may not solve your problems.
Post again and let us know what you find out.
Edit: I see gonwk’s provided an alternate route. Good.
