OK – I used Architect Pro (trial) and successfully created a blu-ray disc (but it took 6 hours for 90 minutes of SD mpeg2 files)! But it is not recognized on my new Sony blu ray dvd player, which reads the disc but shows no menu. I used a new buffalo burner (it claims 6x speed but only burned a 6x disc as 2x)!
Any options? In architect I just did a file-new and chose blu-ray for the dvd type.
