Zune Copy Protection Question
I'm pretty new to the portable MP3 player scene, so bear with me a moment. What are the issues to consider when buying one of these regarding copy-protection? What I'm most interested in is the fact that I've got a ton of MP3's and a few videos, so are they going to work on a Zune? Most of my MP3s are ripped from CDs; others are from "other" sources. I know there are some formats out there that can only be played on the intended hardware, using the intended marketplace software, ie. iPod + iTunes. Is that correct?
I just want to make sure I don't need to go re-buy all my songs when I get a Zune.
