Problem with SD

I have a 4 gig fuze with latest firmware.

Just got a SDHC it will play all the music fine, except I have no album art or info about the song on the fuze. All the music thats sync’ed on the internal will have this info. I am using Windows Media Player for Sync, the original files are lossless WAV’s. I like converting them to good quality but not lossless WMV files.
 I have been typeing in the album info myself , and im wondering if this is a problem with WMP, the card, or the fuze? If this is unfixable…how can i add album art to the WMV file?
