Download the latest drivers, run the installer. Get the CD with your DVD
decoder on it, insert it, run the installer.

I too have the same error. Windows media center can see and play the dvd,
but WMP 11 cannot. I updated my video driver, ran the decoder check-up
utility and it showed no preferred codec, but several were 'acceptable' but
no decoder was recommended as 'preferred'. Checked for updates, none found.
Downloaded lots of codecs, but have not hit the right one for standard dvd
viewing...??? Cannot pull the codec off of the cd that came w/the pc because
it simply downloads the OEM version of Roxio/Sonic onto my Dell. I have
upgraded to Creator 9 and it seems to work. My only issue is that WMP cannot
see dvd's to play them

Chris- I have also been to your blog and saw that too many decoders may cause
problems for WMP. How do I select ones to delete? I know how to do that
now, deleted some divX and reinstalled them...didn't make a difference

Under WMP's Help:About:Technical Support Information, what DVD/MPEG filters
are listed?

Speaking for myself only.
See http://zachd.com/pss/pss.html for some helpful WMP info.
