Jerry, first of all congratulation: to be your first project, it seems really hard to realize, even for an experienced restorer, so kudos to you!

Now you know how tough could be to put in sync more than one track, especially when it's from analog sources... but it seems you are making a good job.

For release time: if you think to make a Blu-ray project, and as the total space is around 90GB, you could always release a BD-25 for every season, hence every season when is ready.

Last hint: if you want to make menus, I strongly reccomend to use MultiAVCHD, the only free authoring software that could allow you to make BDs with menus.
