I only can speak from my own experiences:
With good working conditions Burners and using diff media. (as it got old)
I always have diff formats of DVD blank Media with me all the time.....and experimenting around I come out with this......maybe not 100% accurate but I am close to it "related to diff Media use only".
Now the Burner can fail for others reasons like:
Pour Factory Quality Control on new Burners.
Laser out of calibration.
Firmware issues.
Pour ventilation and over heated.
Bad installation.
Broken peaces.
etc.
You have done nothing with your computer - no updates of your burning program or similar actions.
You are using the same media as before and even the same spindle of media.
When you insert a DVD - nothing happens and the only thing you hear is a scratch sound.
In Windows Explorer you can see the contents of a CD but not of a DVD.
You can still play and burn CDs.
When you try to burn - it will only reject your inserted media and ask for a blanc disc.
Pick it to pieces and cleaning the laser head don't help.
The logfile reported "Power calibration error". "
The above is my experience too. To Mrguss, I appreciate your contribution. One of my HPs is so old its first burner REQUIRED DVD-RWs. They weren't that reliable. You could erase them by touching them with a fingernail of static electricity. What happens to reveal they no longer worked: They will still analyze disks properly I think, but that doesn't do any good because the ISOs they create, produce DVDs that stutter and stop or end before the film is complete, or are missing whole sections.

I didn't mean to sound as if your post wasn't useful, I should've added that the reason certain discs won't work with older drives is in fact the firmware you listed as other failure reasons. An old burner that only ever expected to see 4x disk speed now has 16x disc put in can almost be expected to have problems. This is when to update firmware. I'm not saying this is the only reason you had those issues MRguss, just showing an example. But now we are really off-topic :)

So I have had two swipes even though deep analysis has never been checked. I considered my burners to have failed in the two HPs when I wasn't getting complete disks anymore with even disks whose files didn't even need to be squeezed.
Like I say, I never turned deep analysis on, yet in one machine it took twice the amount of time to encode and analyze the files (Dell 1500 inspiron AMD chip) compared to two HP Pavilions (Intel chips).
