It used to be worse. When I first started the world of DVD burning 15 years ago, there was only 1x media. And what would invariably happen is you'd get to 99% complete on a burn and then it would crap out, wasting an hour's time.
DVD Copy probably didn't do Verifies or back when you were using it, the Pioneer was still alive.
The easiest way to determine if you have a firmware update is open ImgBurn in write mode and select the drive you want to check the firmware for from the drop down list of target drives in Write mode. Right click on the drive entry in the bar and choose Check for firmware update in the context menu. It will tell you your current revision before opening your web browser to the firmware site ImgBurn checks. Now, sometimes the site won't find firmware for your drive based on its drive string. USB drives are notorious for not being found on that site.
And if you want to check the model manually, open ImgBurn and in the log window that displays opening information on startup of ImgBurn, find your drive listed in the log. It will tell you the drive model string and firmware version currently installed. Now, sometimes model drive strings are vastly different from what the model name actually is. But, it beats cracking open the tower unless you have to.
