Guys you really don't need to link Flixster and Vudu unless you got free movies by signing up with their services. What you need is to set up an Ultraviolet account (think of it as the bank where you hold and store your movies). Now sites like Flixster, CinemaNow (Best Buy brand), Target Ticket (Target store brand) and Vudu are basically the ATM machines where you can get and play your movies. Most smart Bluray players, Smart TV's and tablets devices and computers can play all UV movies but Vudu is the only one that offers up to 7.1 surround sound while others are still in stereo. There are some Smart Bluray players that are exclusive to Best Buy CinemaNow app and won't play Vudu or Flixster so make sure you buy a Smart player that can play Vudu for the surround sound. Also Flixster, CinemaNow and Target Ticket don't offer as many titles as Vudu so although you can load hundreds of movies onto your Ultraviolet account not all titles will be able to play via Flixster or CinemaNow or Target Ticket ( the movie Line of Fire with Clint Eastwood is an example) but Vudu has always shown every title I've loaded and I'm already up to 560 movies.
Now another mistake is when I first started loading movies I thought of Ultraviolet as a tablet based player only so initially converted a bunch of movies in SD only as my iPad 2 is SD only then I realized that my PS3 had the Vudu app so everything I have is now in HDX format and I had to go back and pay again to convert my SD titles to HDX so always go with HDX.
You can buy a new Bluray movie that has the UV code and load it that way but there are several reputable sites that offer just the UV code for sale for 5.00 without having to go to a store or buy the physical media. Hell I bought Captain Phillips days before it hit the store in HDX format for 5.00 online. Since my entire family is linked to my account they get the bonus of also seeing every title I load the moment it gets on Ultraviolet. Also Everytime a linked family member adds a movie it gets loaded on my UV account also.
Now there are some movies that are exclusive and you have to buy the actual physical disc to get the UV code as you can't buy it online or even through Vudu dot com (Wal Mart's "The Great Escape" exclusive is an example. If you can find it at Wal Mart buy it cause it can't be had anywhere else. Disney does offer its movies for sale but they want you to pay full retail disc price just for the digital copy which sucks. Also Vudu offers "Disc to Digital" where you can load and up convert your movies to Vudu and UV for a small fee. 2.00 for DVD to SD digital copy, 2.00 Bluray to HDX and 5.00 for DVD to HDX up conversion. You can do this from your home computer or take your discs to Wal Marts photo center and have them do the conversion. Now Wal Mart is limited to title selection in store so if your movie has a common title they may not pull it up so its best to create your Vudu wish list on their disc to digital site and choose your resolution and when you go to Wal Mart all your titles will automatically show up and the clerk won't tell you your titles not available when you know that it is. Always fill out a wish list first saves on aggrevation.
The other thing is once your logged onto Vudu Disc to Digital site looking for a title it may not show up but once you log out and check the same title it shows up. So log out then look for title choose resolution then it asks you to log in once you log in that "missing title" will be on your list. Don't ask me why this happens but it does. Happened for every Resident Evil I tried and the movie "Red".
The other good thing by linking your Flixster, CinemaNow, Target Ticket and Vudu accounts is when you sign up for each service they give you free SD movies (normally 10) but Vudu gives you 5 free HDX movies when you sign up. So by setting up accounts you get 35 free titles to load on your Ultraviolet account right from the get go. When linked family members join you get all their "free" movies also but the titles are older movies.
