? It's not legal to buy DVDs now? Because it's most certainly legal to circumvent the copy protection on a DVD you own to be able to play back its contents in the US.

There's no such thing as DRM-free commercial video right now, so I suppose it's all a matter of how you want to play back what you buy. At the moment, DVD and BluRay offer the best quality SD and HD image and sound, potentially at comparable prices to download-only options.
