I've been using AnyDVD HD for a few years, but I have not had a Blu-Ray reader or writer until a couple of days ago and I have no Blu-Ray discs yet (Netflix, hurry up!). AnyDVD works great on DVDs and claims to work with Blu-Ray and HD-DVD formatted content. It's not free, unfortunately, but it's supposed to uncripple the format.
And before I get to far: I'm not a pirate, my use of AnyDVD HD is simple: I have a single SageTV Media Server (HTPC/DVR software) and I use extenders to play all of my video content on three televisions (meaning my TVs have one tiny low-power box yet all of my TVs can play a DVD or watch recorded content and live TV from my noisy HTPC tucked away in a rack in my basement). Without AnyDVD, I can't put a DVD in the basement server and play it on an extender upstairs. I was hoping to do the same with my new Blu-Ray player.
