It took some time to work out most of the bugs, but Vudu is finally expanding its beta of its home-based disc-to-digital service. The idea and the price are still the same as when the private beta launched, but what's new is support for OS X, plus an improved user experience and disc identification powered by Gracenote. We gave it a try and found the process couldn't be any easier or more straight forward. To get others to try it out, Vudu is giving away the first conversion on the house and if you're willing to convert ten or more movies then you'll get a 50 percent discount. After converting a DVD to HDX we were instantly able to turn around and start watching it, far faster than any disc ripping software we've used. Add in the newfound ability to download movies to iOS and Android devices and UltraViolet is really shaping up -- though we're still waiting for that common file format to move copies between devices easily and single sign-on to fix the login mess.
