Welcome to the Q&A Forum

The issue is, this isn't what the map location feature was designed for. If you take this approach, you're ultimately attempting to trick YT into thinking that your content is unique when it isn't and this will not be looked at kindly by Google. While your approach may work for now, the YouTube videos wont rank very well and you are putting yourself highly at risk of a spamming penalty in the future. I think the single video option with dynamic page could definitely work, but it might be tricky to get the one page to rank 100+ geographical terms An alternative might be not using YT to host, as Google can see the analytics info for YT and give negative quality metrics based on the fall out rate of the YouTube vids; which will inevitably be extremely high if it's an advert. I would recommend using Wistia - http://wistia.com/ which Moz use, as they have an automatic sitemap submission service which is very nicely put together and easy to use if you're scaling the content over a vast franchise. You could upload multiple versions of the same video with Wistia and create unique pages for each franchise location and then you should be able to get blended results for multiple geographical terms - especially if you hook the pages with the videos on to the Google Local listings. All that said, Google will be able to crack down on duplicate video in the future. Audio wave matching isn't that hard - they already do it for YouTube and will do it for other services in the future. If you can get away from totally duplicated videos, especially on the audio front, it would future proof you from Panda and other dupe content smack-downs. Maybe get a different actor (with appropriate regional accents) to do the VO for each franchise?
