I found this after many hours of searching this problem, yes i found it on dells site as roxio obviously don't care enough to publish this...
Yes, 15mb is a big patch, it is actually a patch to update 'drag to disc', but as I said before it will allow you to remove DLA no matter what attempts have been made to uninstall it before, I tried the XP reg changes and managed to kill vista bad enough to require fixing via booting from the DVD.
Both DLA and drag to disc can be removed after the error has been cleared.
As long as it works to stop the errors, 15mb is a small price to pay, I'm happy , very happy!!!
Hope it works for you all.
