I just took all of my content protected, downloaded, paid for WMA files and ripped them into Windows Media Player as WMA lossless files. I had burned all of them to a cd disk. I loaded one of them in hoster and it played perfectly. I don't think hoster can import a protected file. You can burn them to CDG's then rip them into Windows Media Player as WMA files and hoster will load them.

P.S. There is probably no way hoster could load content protected files because it would have to decipher them.
