There are not alot of adult blu-ray titles due to the cost of producing blu-ray titles. I just read about a free blu-ray encoder that will help produce cheaper blu-ray discs. Would this help?

First Free Software Blu-ray Encoder
The x264 project has released an entirely free Blu-ray encoder. It even comes with a torrent containing free content for you to view just incase you didn’t believe them ;)
With x264’s powerful compression, as demonstrated by the incredibly popular BD-Rebuilder Blu-ray backup software, it’s quite possible to author Blu-ray disks on DVD9s (dual-layer DVDs) or even DVD5s (single-layer DVDs) with a reasonable level of quality. With a free software encoder and less need for an expensive Blu-ray burner, we are one step closer to putting HD optical media creation in the hands of the everyday user.
