We use Vudu for streaming rentals. There are times it does not work or has bandwidth issues and drops to 480 or lower resolution to keep from buffering, just like nextflix and everyone else. These issues usually happen on weekends and other high use times and are dependent on your IPS. If you are planning a night of anything more than casual watching, you'd be better off on purchasing (or renting) a DVD. Imagine having your 8 year old over with several friends with the promise of watching a movie just to find out the service is down or slow. Or that 3rd date with someone special and your Vudu keeps buffering! If purchasing from Vudu and keeping in your Vudu account, keep in mind they will have server crashes, server changes, upgrades, etc. Your account could be lost, deleted or damaged. They will be happy to reestablish your account but if you don't have receipts showing the movies you purchased, your out every purchase you made. To make things worse, they do not e-mail receipts of purchases, they keep that in your account... the same one that may have been lost or damaged! Bottom line, Vudu is great for casual rentals on any night that if things stop working you won't be upset saying, "Oh well, time to go to bed", but for anything more, you really should think about something more reliable. Keep in mind, these comments apply to any on line streaming service, not just Vudu.
