Lifehacker's guide provides a cross-platform Windows, OS X, and Linux solution to getting your Blu-rays onto your computer.
Having a massive Blu-ray collection sitting on your shelf - or shelves as the case may be - is an impressive sight, but going and getting something off of the shelf is less convenient than simply pulling up the file on your HTPC. Ripping those Blu-rays can be a pain, but the good folks at Lifehacker put together a guide that should help out.
You'll need a pair of programs, one for ripping and one for encoding as well as plenty of hard drive space and, of course, a Blu-ray drive. Once those are installed it's a three step process to get your movies onto your hard drive in whatever quality you desire.
Depending on your preferences, you can cut down the space taken up by your Blu-ray pretty significantly, but if you prefer to stick with a 1080p picture and DTS support you'll end up with something a bit larger. Either way, you'll be well equipped to enjoy movies through your favorite media player.
