The service will allow you to upload certain DVDs and Blu-ray Discs to their site and make them available online. The cost for DVD transfers in standard definition is $2 per disc. The price is the same for transferring Blu-ray Discs to their HDX (1080p) format and if you want to convert your DVDs to HDX it costs $5. When I signed up, they had a deal that made it cheaper for a few months, but I don't think they offer it any more.
The main downside is that they do not have all movies on file, so if you have a large library, I can almost guarantee that you won't be able to convert them all. Also, some DVDs can't be converted to their HDX format.
Other than that, you simply download their VuduToGo app on Windows or OSX and load a disc. Assuming the movie is in their library, it will then give you a choice to use HDX or standard definition for DVDs, and after you choose, it will allow you to copy it. It works fairly quickly and I had very little problems with the software.
Once you have your movies loaded to their site, there are several ways to access them. My main use for these files is streaming with a Roku, but the Vudu app is available on many products (iPad®, iPhone, computers, Xbox 360®, PlayStation® 3, certain Blu-ray players, and certain HDTVs). Once you sign in, you will see every movie you have uploaded and you can instantly stream them.
For on the go, they have iPad, iPhone, and computer apps that will allow you to stream the movies. However, the best part is that you can also download the movie to these devices and have them available when you are offline. For my iPad, it took about 20 minutes to download a movie.
I should mention that the quality of these files (HDX) is really good, but not Blu-ray quality. For me, once I see a movie in its best format, I don't mind watching it again in a lower quality. If you are someone that only wants to watch Blu-ray, you may want to rent one of their movies in HDX before converting your movies to be sure you can live with HDX quality.
All in all, I really like the service. The ability to convert DVDs to HDX quality, the ability to have a backup offsite, and the ability to download the files to a device for playing back when you aren't online is fantastic.
