Some of that stuff has nothing to do with drm and there is no way microsoft would make it so you couldn't play unprotected files because no one would buy the operating system.

They are certainly thinking about it. With the pressure from the RIAA and others, I can see that they may. Ok, you have unprotected Mp3's and windows wont play them. No problem, just stick in your original disk to verify you are entitled to have them and windows will fix them so you can play them.

Oh, you dont have the original disk... Shame...

MS is coming down heavy on piracy. Already with HDTV you need TC components and heavy DRM. There is pressure from the US networks, hollywood, and other content/media providers. MS is working with a lot of content providers....

MS are dying to break Mp3's back. Have been for years... WMA for all...

Mp3 is probably the most popular format and is used for most audio files on the internet radio broadcasts are avalible in mp3 and there is no original disk for them so the system could never work and which is why they won't implement it. Otherwise they'd have to ban every audio file type because you could just rip cds with another format like ogg. In the end the only extra bothersome protection vista will add is AACS and protected outputs for drm files and hdcp, AACS has already been bypassed though.

The idea behind DRM isnt to stop you ripping CD's to your machine. its about stopping the CD's you ripped being played on another machine. Or you making infinite copies. Or downloading copies from p2p

Mp3 is the most popular format due p2p and piracy, not because its the best audio compression codec. Its not. Its poor at its job.

There is nothing to stop internet radio companies broadcasting in any format they like. Besides, doesnt the law say you have to delete broadcasts after a specific length of time anyway...

It isnt just about mp3. its about all media content.

agree, if they made it like the op says then they would lose out on a lot of sales, the more they push the more people will start to use linux.

Mp3 is most popular because thats what all the digital audio players support universally not because of piracy, it isn't going to be implemented because no one would buy vista if it was. Radio companies are not going to start broadcasting in other formats because, the os does not support formats like ogg nativley and because mp3 does not require as much processing power as more heavily compressed formats. If they didn't allow any non drm media to be run then no one would be able to use their digital camcorder or audio recording equipment with windows and send videos to friends.

Erm... so don't pay ££££ to the DRM companies just for the privilege to use their protected formats and continue to rip your CDs with more traditional non-DRM methods? Piracy sites most certainly won't drop what they're doing and switch to DRM - it defeats their whole purpose...

DRM is for companies that want to sell protected content (i.e. iTunes, for a fairly bland example) without the worry of it being pirated 100 times over. It will make way for all new multimedia experiences on the Internet because no longer are company exec's going to be shaking in their boots about piracy.

Nobody is forcing you to use DRM.

As NathanE has said.

DRM is to protect what you buy,

Its not stopping downloads or other uses, its about bob buying a track from itunes. and then shairing it with his mates so they dont have to buy it.

Its not such a bad thing, and dont worry your porn downloads will be safe

Thats a little bit inacurate mate. DRM is nowhere near heavy enough in Vista to stop unprotected MP3s playing!

Besides, what about those few legal sites that sell unprotected MP3s? there is a couple around still..
