Vista Media Centre and ripped DVD?

I have Windows Vista Premium and Media Centre all set up. I also have a lot
of music DVD's I have bought an ripped to my hard drive.
When I put the DVD in a drive Media Centre see's it and plays perfectly,
but, I cannot get it, in any way to see that there are DVD's stored on my
hard drive. Is there any way I can change this? The individual DVD folder
contains all the correct files and folders. PowerDVD and WinDVD both play
them fine, just WMC won't.

Also I have a lot of DIVX'd videos stored too that WMC won't acknowledge are
there. Windows Media Player will play them ok, so why not WMC?

Thanks

Barry
