This part is claiming that your burner was unable to figure out what the
correct power level is for writing to the media.  This is entirely
controlled in hardware, so there is no legitimate reason why your
version of cdrecord should have any effect. It is almost always caused by:

* Bad media
* Bad hardware
* Insufficient power supply

You've basically eliminated #1 by using the same media successfully, and
#3 isn't the kind of thing that just crops up, so I suspect your
recorder is starting to fail.  (It could be as simple as a dirty lens).
 The only question is why older versions of cdrecord continue to work.

Can you post the output from a successful run on the same ISO as this?
It would be helpful to see if cdrecord is using different settings for
the different versions.  In particular, if it defaulted to a lower burn
speed, or didn't enable BURNFREE by default, those may change the power
requirements.
