The Difference Between Blu-ray and HD-DVD in 30 Seconds

The difference between Blu-ray and HD-DVD is simple: capacity, as in how much stuff you can put on a disc.

Blu-ray HD-DVD
HD Video Capacity ~5 hours ~3 hours
Data Capacity 25 GB 15 GB

In short, blu-ray holds 40% more stuff. That means you can back up more photos on your computer and watch more episodes of Lost on a single disc.

  • One format is not prettier than the other as they both use the same techology for video. If anything will affect the level of pretty, it’ll be how good the studio did at scanning in the film.
  • Ignore reviews of the current players available. Both players are clearly glitchy and should have spent more time in quality control. They rushed them out, but time will work out the kinks as well as bring the prices down to reasonable levels.
  • Ignore the Current Prices. The marketplace will bring the crazy prices you see today down the exact same way it did with the VCR and with DVD. In a few years, you’ll see video on the evening news of old ladies getting trampled at Walmart to get their hands on a $30 next-gen disc player, regardless of which format it is.

So, what should you do if you want to buy one now?

Don’t. Find some other way to spend your money. Feed an orphan. Save a whale. But don’t buy a glitchy premature disc player that will be available much cheaper in only six months.
