vista wont read any DVD+RW

I noticed this after I upgraded to sp1. I'm using 32 bit ultimate. I went to
delete the upper and lower filters and they werent there. I suspect that may
be a part of the problem.

When I insert a DVD+RW into my DVD READER it shows the file "Desktop.ini"
and nothing.

When I insert a DVD+RW into my DVD WRITER it shows nothing. and that's if in
actually shows anything. Usually it just slows everything down.
