I have reinstalled WinXP Pro this time with SP2. All seems to work normally and I then realized that I didn't install WinAspi. I use Nero 22.214.171.124 and Sonic MyDVD 6 Suite I am able to burn with no problems. Autorun works fine with DVD's and CD's that already have data, etc. on them...the only issue is that when I insert blank DVD's or CD's...the popup window asking me what to do no longer works. Seems more a Service Pak 2 issue to me.
