I am lazy. I don’t mind admitting it.
While blu-ray picture and sound quality are unsurpassed (at least until 4K becomes established), if I’m going to put on a random movie to watch, I’ll turn on Vudu (or Netflix or Amazon or Hulu) rather than get my lazy butt up and find the blu-ray. This is made easier by having most new movies come with digital copies that work on Vudu.
Wal-Mart has a program where some percentage of the films they sell will automatically come with a copy if you enter your receipt into their savings catcher. This has never worked for me personally but perhaps I’m not purchasing the right films.
What does work is that you can download VUDU togo on your computer and convert DVDs and Blu-Rays (if you have a drive). They charge $2 per movie for blu-ray to HD or DVD to standard. They charge $5 for DVD to HD. This is fine for a movie or two but gets pricy if you have more.
Thankfully, Wal-Mart will give you half-price if you convert ten or more titles. Conversion is easy if a bit time consuming. The time consuming portion is that there are a ton of titles not supported. Still it is a nice tool when it works.
Vudu also makes it easier to watch a marathon without getting up.
Pardon me but I’m queueing up the first Alien movie.
