By the way, has anyone actually tried making and exporting the menu in multiAVCHD? Because here it says this:
Menu support:
Maximum number of titles: 252
Maximum number of hidden titles: 251
Maximum number of subtitles per title: 32
Maximum number of chapters per title: 96
>> Maximum number of audio tracks per title: 32
Welcome screen / Intro title: 1
When you preview the menu in multiAVCHD, it shows only six tracks in that small box but that is only static preview with no actual functions, so I thought maybe, when you create the menu, it might actually scroll down to the others but I have yet to figure out a way to test this without actually creating and burning the whole disc.
