I didn't mean to sound like I'm telling you what to do with your edit, but if you're really planning on having half a dozen foreign tracks included, wouldn't it be better to have a separate multilangual version of ESB:R?
An extra gigabyte for the video might not be *that* noticeable, but it can definitely add some extra detail on bigger displays.
Your call in the end, but I just hope you'll at least consider it :)
Ady says ANHR was only 6 GB and looks great on larger displays, leaving over 3 GB for just extra audio. If people want to watch it in English on a large display, they'll be able to use the AVCHD version which is pure 720p goodness.
