DRM restriction of the Zune Marketplace1. Music from Zune Marketplace is offered in DRM-restricted WMA format (2-pass CBR @ 192kbit/s) or non-DRM MP3 format (up to 320kbit/s) for a per-song or per-album fee, or via Zune Pass monthly/quarterly subscriptions; videos are also DRM-wrapped WMV can't be downloaded via Zune Pass.
2. Songs downloaded from the Marketplace are restricted by DRM similar to yet slightly different from Windows Media Centre's PlaysForSure DRM, meaning that songs purchased from PlaysForSure partners could not be playable in Zune Software or on the Zune device, although the reverse is true.
3. Zune Pass downloads cannot be burned to audio CD unless purchased, and become unplayable if the subscription lapses, or if in the future Microsoft should decide to discontinue the service. The Zune pass allows for 3 Zunes to share the downloaded DRM content as well as the content to be downloaded on up to 3 computers.
4. If you want to enjoy your Zune Marketplace purchased content on a new computer, you can download songs that you purchased five times for WMA files, and just once for MP3 files (including your initial purchase download). Videos can only be downloaded once.
The same situation from Apple iTunesLike the .m4v movie, as well as the .m4p music and the .m4v TV shows, from iTunes are copyright protected the same by Apple's incoperatible 'Fair Play' DRM system, which prohibites other device but iPods playing iTunes content. Furthermore, the iTunes rented movies have dead limitation to watch within 30days and 24hrs (once you began to watch it).
Tomato tomato the other online store like Windows Media Centre, Napster, Rhapsody, Nokia Music Store, Spiralfrog, Bearshare, eMusic, Puretracks, MusicGiants, CinemaNow Movielink, Amazon Unbox,
So unless Zune folks has a third party
DRM Removal Software to strip the license protection and convert media formats to Zune compatible .wmv, .mp4, .m4v, or H.264, they can't enjoy those digital content, as what the big brands said, "On The Go"!
Here this step-by-step guide which is divided into two parts FYI:
Part 1: remove DRM from Zune Marketplace and protected WMA WMV from Zune Pass1. Free download this
DRM Converter, install and luanch it, the default settings work well with your PC, you don't need to make anymore configeration.

2. When come to the main interface, you can directly drag-drop DRM-protected media file to the conversion window, or hit the top-left 'Add' button to import the target files.
Since Zune plays WMV / M4V / MP4 / H.264 video files with peak 720 x 480 pixels and 30 fps, if you're picky on the output quality, the function module 'settings' can help you with it by offering adjustable parameters covering Bit Rate, Resolution, Aspect Ratio, and Frame Rate as well.

Part 2: How to play DVD movie on Zune playerIf you want to transfer DVD movie to Zune, this
DVD Ripper for Windows can help to crack DVD CSS protection, split DVD movie to clips, and convert them to Zune compatible audio & video formats.
