Which is better … streaming content or buying shiny plastic discs?
It’s surely an unfair comparison because the constraints of a service like Netflix (delivering uninterrupted video over a range of network qualities) are very different to delivering content on physical media. But I was looking to justify my purchase of Battlestar Galactica (BSG) on Blu-Ray so here’s some screen captures as a very unscientific comparison. The screen captures are only approximately the same frame on each media, but should be close enough for a rough comparison.
The Netflix screen captures were done streaming on a fibre internet connection using a Mac with Silverlight installed, but with no other adjustments. The Battlestar Galactica Blu-Ray claims to be “High Definition Widescreen 1.78:1” (but doesn’t define high definition further … is it supposed to be 720p or 1080p?).

In this instance, Netflix does a pretty good job, although it looks a little blurry. BSG is probably a bad choice for showing off Blu-Ray in comparisons: it’s heavily processed to make it look grainy like film, and almost every single scene is very dark. I doubt it was shot on the latest HD cameras, either (the miniseries first aired in 2003, the full series began in 2004). But since more recent series like Game of Thrones aren’t available on Netflix, this is the best I’ve got for comparisons at the moment.
Of course, even if the Blu-Ray and Netflix versions were identical, a big benefit of those shiny plastic discs is they can be used off-line and don’t require a continuing subscription.
