#DVD R NOT RECOGNIZED INSTALL#
A DVD burner/reader manufacturer who knows this may install reading circuitry that is more sensitive to compensate. This further reduces the amount of reflected light when there is a hole, decreasing the SNR even more. Maybe the writing laser is weak or doesn't stay on long enough, and not enough dye is etched to make a full-size hole. If the DVD burner is weak or marginal, it might not burn a very big hole. They use a phase change material instead of a dye layer, and their SNR is on the order of 10:1. These are more difficult to produce so are a lot more reflective, and the SNR is only like 100:1. DVD-Rs have to use a photosensitive dye to allow a write laser to burn a hole, but not sensitive enough to burn when hit with the read laser. Mass-produced DVDs (and CDs) physically alter the reflective layer itself, and have something like a 1000:1 SNR (I don't recall exactly, these are ballpark order of magnitude figures from a very hazy memory). The difference between the amount of reflected laser light when there is a hole and there isn't is effectively the signal to noise ratio. No dye is a perfect absorber however, so there's always a tiny bit of reflectance. (Or the other way around - I always forget which is which). If there is no hole, the dye layer absorbs the laser, there is no reflection, indicating a 0. A laser shines through the hole and bounces off a reflective layer indicating a 1. Optical media works by burning a hole into a dye layer. Or the DVD burner did not make very good burns. So they strong-armed a lot of manufacturers into crippling them so you couldn't, for example, burn live TV show broadcasts to DVD and share them with your friends. Hollywood saw these standalone DVD burners as a digital version of the VCR, and they hated VCRs with a passion. Then convert it to another more widely supported format (preferably purely digital files). Your only solution then would be to find the same or similar model which can read the format. I see two possibilities here: Your DVD burner used some sort of proprietary format that only it could read. So even if the computer couldn't play the videos, he should at least be able to browse the files on the discs. Unlike music CDs, DVDs are just computer data discs with media files written on them.
#DVD R NOT RECOGNIZED WINDOWS 10#
I don't think Windows 10 Media player allows you to play DVD's anymore, so that might be the issue with your compuer. You should try downloading a media player from online and seeing if one of them will work.
