XP home doesn't have GPedit.
However I may have perhaps found the culprit.. I took a walk over to Kelly's Korner XP Tips, and she says to disable the recording directly on the drive, by right clicking /properties/recording, and disabling it.
I think this is what was resetting the NoCDburning reg fix i made... Because the two settings were fighting eachother.
I suspect this might have also been the source of my drive letters resetting themselves... As a safeguard to have the entire algorhithm fail because of conflict, reset all drive letters and settings.
If you've looked at my other topic, with similar title to this one "Yet another annoyance
" , you can see that I explained that my drive letters were resetting themselves scince 2 weeks, seemingly randomly.
Well I remembered monday night after I posted that right after I had rebooted to reset the CD burning to my settings, the drive letters went. And after I reset my drive letters to what I wanted it to be, it was my cd burning that went again, reboot after reboot.
So I'm convinced now that the two problems were linked, and that by disabling it directly in the drive settings ( which I had never thought of before seeing kelly's site ), the conflict may be gone.
I'll keep you advised.
