I've bought a great cheap mp3 player, my requirement is to play PLAC files which it does, not bad at all for £40

Next I'd like to create a playlist that includes MP3s & FLAC Files.

This is done apparently using Windows Media Player 12 and synced to the MP3 player,

but it turns out that WMP doesn't play FLAC files, so can't add FLAC files to the palylist either.

I've added an plugin that let me play FLAC files in WMP & another that made the FLAC files appear in the library , but I still could not add the FLAC files to my playlist.

Even worse since I added the plugin to make FLAC files appear in my library (so I could drag them into my play list), I can't drag & drop any music at all into my playlist!

How the hell do I remove these plugins so I can at least create a palylist with just MP3s in it?

Even better:

Does anyone know of any better addins that could do what I'm trying to achieve?

Thanks in advance
