First forum question, so apologies if the answer is obvious.

I have bought a 8gb media card for my 9000 and have downloaded all my PC music onto it. On my PC I use Windows Media Player which shows all the albums with all the track details. When I look at the 9000 list via Roxio via Desktop Manager it also looks complete, however when I try to find some tracks or albums on my 9000 they are not listed directly but can usually be found under "Unknown". Why is that ?

I admit I probably have a mix of music types i.e Itunes and MP3

Cheers

Jim
