x264 is a free AVC encoder that is best-in-class and thanks to compliance testing from the Criterion Collection now supports Blu-ray Disc encoding. GDMX has also vetted x264 for BD use using the Eclipse Verifier in 1080p24 and 1080p/i30. This page deals with the most common scenarios for Blu-ray authoring. Many commercial discs from well known names have been made using the guides here.
