Interesting. OK, so it looks like the old DVD-ROM drives are the
problems if they have problems reading both burned DVDs and CDs.

Frustrating. Funny thing is that I avoided DVDs because of this. I
finally got my own DVD burner last December, and still run into this.

I tried it on the CD-R that my older DVD-ROM drives couldn't read
yesterday and still same problem. I guess the drive thinks the CD-R
isn't in the drive. Heh. No problems for my new Sony Optiarc drive from
12/2008.

I ran both disc quality and scan disc on this TDK CD-R. Here are the
results:
General Information
Drive: Optiarc DVD RW AD-7220S
Firmware: 1.01
Disc: Data CD (CMC Magnetics)
Selected speed: Maximum
C1 Errors
Maximum: 29
Average: 1.65
Total: 6638
C2 Errors
Maximum: 0
Average: 0.00
Total: 0
Jitter: -
Scanning Statistics
Elapsed time: 2:15
Number of samples: 4018
Average scanning interval: 1.00 sec
Glitches removed: 0
ScanDisc showed all green (100% good).
I will try my other burned CDs and DVDs later on. Also, I do use verify
feature when I burn discs but I think that's useless (all came out good)
because it will be fine for THAT drive and not others like DVD-ROM
drives. :P

I'm only giving ideas, not accurate definitions! But at a rough guess
I'd say that 16x drives would probably not count as "early".

It all makes a difference, and has some effect. I'm merely giving you

What about getting a USB drive and connecting it to the machines as needed?

Thats not that early.

Some faults have nothing to do with how much they are used.

Yes, it does matter what brand of DVD burner and DVD blanks
to get. I prefer LG burners myself, significantly less picky about
the media, but you should still avoid the cheapest DVD media.
Like I said, CD media is now safe enough to buy anything.

Yes, and replace them with burners, no point in DVD non burners now.

Not relevant to your thread, but the Optiarc wanted to burn 2.4x
Verbatim DVD+R DL's at 4x. But if I let it, it makes a section where the
quality drops to zero, though it verifies ok on the Optiarc. At 2.4x it
comes out great.

Maybe the old drives are just too old. I had a 4X DVD writer that was
great except it choked on rented videos, unlike later models. But even
between a late model Pioneer and Optiarc, I rented one movie that only
the Pioneer could read.

Pressed disks give a far better signal and do age very slowly.
The reverse for both is true for self-burned disks. The RW formats
age better, but have an even worse signal AFAIK.

Hmm, I never paid attention to the speed burns. Maybe that's the problem
if the speeds are mismatched?

USB is slow. Internal drives are way faster.

You have got old computers, and old drives - they are slow too. Unless
they are pre-USB 2.0, then USB is perfectly good for light DVD usage.
If you think an external drive is too slow, and your internal drives are
too old, then you can simply replace all the internal drives.

On the Disk Quality tab, near the bottom right corner, it says "Quality

If they show good quality it's ok. If not, try a lower speed. I use 12x
for backups on 16x media.
