I have a Blu-ray file (one I own and wanted on hdd for easy transport) on my computer. I want it to play on my Xbox 360 and it won't because it has 5.1 surround sound. Inside the file is the 2.0 audio track separate with instructions on how to merge/change it using a program called Yamb. The only problem is that it's Windows only. Do any of you know a program (preferably free) that can do this for Mac? I have Toast Titanium 10 and toyed with it for awhile but couldn't figure it out. Thanks.
