I'm not sure what you're talking about. Care to explain? I've ripped lots of audio CD on Vista without issue. Are you sure you understand DRM?
There is no DRM when ripping CDs on Vista, either. iTunes runs fine and will rip CDs to unencrypted MP3. Exact audio copy will work just fine.
There is a massive load of FUD being dumped about Vista.
The DRM only applies to content that has DRM -- HD-DVD, BluRay, purchased music and video and CableCard recordings. Media that does not have native DRM, like over the air HDTV, MP3s and the like do not have DRM added by Vista.
Because of US copyright laws, if you want to run HD-DVD, BluRay or other new "premium content" on your computer, you have to play by the content providers' rules. We haven't heard from Apple yet, but if they want to support BluRay or HD-DVD, they will have to add the same kernel-level DRM support.
