That error, Sense: 04, ASC: 44, ASQ: D9 is a hardware error "Internal Target Failure" reported by your drive back to the computer. The names of your drivers (PX.dll etc) are normally reported after the error number for your convenience, but are not themselves the cause of the error.
Do an Internet search for Internal Target Failure and you'll see the sources are pretty vague on what causes it and how to fix it.
Some people report success by getting better quality blank discs, others have had an improvement by cleaning the lens in the drive. Your burner is relatively old so might benefit from a lens clean, but as I said it's all pretty vague.
If Jim's suggestion of reinstalling the Windows driver doesn't help, I would suggest you check if your old drive is being disabled by the different conditions and timings being imposed by the changed software (Windows 8 and/or Roxio). It's easy to check.
-Prepare your DVD as before, but "burn" it to an ISO image instead of a disc
-Burn that ISO to disc with another software such as the free, small, and safe Imgburn (from here)
If the ISO can't be burned with Imgburn your old drive may be incompatible with Windows 8. If it burns without error you have a solution.
