I’ve used the Mainconcept and it was ok.
I am using FCP Suite 2 to edit.
I then use compressor’s HD DVD 19Mbps MPEG2 setting to encode the files.
To finish I use Adobe Encore CS3 to create the BLU-RAY discs for the project.
Please note that most Blu-ray players need a firmware upgrade to play the burned Blu-Ray discs, these are available for download on the players manufacturers website.
