What does "Enable WMA Playback" do for my PSP?

I put music on my psp, but it saids that i have to enable the WMA playback. only problem is that i dont have..

• a wireless connection at my house, and i already tried going to Starbucks and MacDonald's to use there wireless connection, but it stops because of some error, my real question is that can i connect my psp to the Internet without using a wireless connection. like can i just use a usb cord to connect to the internet, if so how? thanks for any help that i can get.

• Answer:

  There's no way to physically connect the PSP to a modem or router. It's wireless or nothing. I think Starbucks charges for their wireless, and I'm not sure about McDonald's. You might want to try a hotel lobby or local coffee house, or maybe a friend who has an unsecured network to see if your PSP connects. As for the WMA problem, it's possible (if you're running custom firmware) to enable WMA playback without a wireless connection. If you're running Sony's firmware, you're out of luck.
