Vudu's mobile app now has the "Disc to Digital" option built-in, so all you need is the ability to scan a UPC code (found on the back of your DVD or Blu-Ray...or from another source

If the title is available, you can "upgrade" from DVD to a 1080p master (dubbed "HDX") for $5 per title. If you are converting a Blu-Ray, it's $2.
Even better, the 1st title you "convert' in the app is completely free! So I'd urge anyone who hasn't tried this already to go for it, try the free movie and see how you like it. It's not Blu-Ray -- but the reality is, a lot of these films are never making it to Blu-Ray, and it's the next best thing.
Disney movies are not included -- really only 7000 or so movies are -- but there are still a LOT not on Blu-Ray that are available in 1080p and are worthwhile (WHAT LIES BENEATH, theatrical cut of THE WARRIORS, TOP SECRET, etc etc).
Check it out on your iphone or Android device! More info here:
