That you are using some form of Windows still being supported by M$ so it's either XP or Vista of some type.
With the introduction of Vista M$ has incorporated DRM or Digital Rights Management which prevents copyrighted material from being copied in Vista at least. The description here that you have given sounds as if under XP using M$ Software it is also occurring to a lesser extent.
The answer here is to either remove the SP3 or the newest Hot Patches if you have not as yet applies SP3 to XP but as it has been available as a Automatic Update from M$ for a few weeks not it is quite likely to have been installed on both systems that you are using.
As SP3 isn't really a Service Pack in the true sense of the word but just a collection of Hot Fixes bundled together it could just as easily be one or several of the Patches that M$ has deployed on Microsoft Tuesday every month for the past 6 or so months that has combined to cause this to happen.
If you do not want to remove or can not remove these Patches you will need to alter the way that you record things and use a proper CD/DVD Burning application like Nero. Easy CD Creator or whatever else you have installed on your computer.
