He has 2 drives. My assumption is based on the very unlikely chance that both DVDRW's are failing simultaneously.
A DVDRW is far more likely to experience problems with a damaged/defective disc.
While that is true, if the drives are a similar make they can sometimes exhibit the same reading problems with the same media. I'm not really stating the drives are failing insomuch as this may just be an issue with the drives used.
You referenced using quality media to, I assumed, make the burn.
Yes
The user hasn't gotten through the reading of the disc.
However, the backup disc is detected and plays on a ps3 and a standalone dvd player.
So, you have a few options:
1. Problem with the drives
2. Problem with the burn
3. Compatibility issue

My backups play on my computer or standalone dvd player, but not in something else. Why?
First, if the backup is playing in a standalone dvd player or on your computer, that means Anydvd and whatever backup program you used worked.
The most common reason why you're having this problem (if the backup doesn't work in a standalone dvd player) is due to a compatibility issue between the blank media you're using and whatever you're using to play the backup in (standalone dvd player, for example). Basically your dvd player, dvd-rom drive, etc. doesn't like the blank media you're using (or if you're using +R media, you didn't change the booktype to "dvd-rom"). You can try choosing other blank media (+r instead of -r, for example, and change the booktype to "dvd-rom")--or buy a different standalone dvd player (or a different dvd-rom drive, burner, etc.).
If you're using dvd-r media and your standalone dvd player gives you a message similar to ""Play Prohibited, please check disc", use dvd+r media instead and change the booktype to "dvd-rom" (see "b)" below).
a) Are you using junk blank media? If you're not using Taiyo Yuden 8x premium, Verbatim, Maxell Plus, or Maxell Broadcast Quality, then chances are the answer to this question is "yes".
b) Click
this and read FULLY (especially take a look at point 4 for more information on bitsetting/booktyping, but all points are very important)
The same factors also apply to why the backup doesn't play in your computer (but there can be other factors including buggy or poorly installed dvd player software, bad drivers, etc.).
It's also possible the playback device/player you're using is slowly dying.
