As I've explained in some of my previous, Blu-ray-specific articles, I prefer ripping my own Blu-ray (BD) discs to purchasing any movie from Apple's iTunes store because:
- (after ripping,) the lack of any copy protection aka DRM: I hate not being able to play the videos I paid for in a third-party and, in several cases, much-superior-to-the-stock-Videos-app player. See for example the excellent, and, in many circumstances (too bright or noisy environment (e.g., a gym) where the maximal brightness and/or volume of the device just wouldn't suffice), compulsory DSP's in It's Playing (dedicated article).
