Hi Jason,
my apologies - I didn't realise I'd already looked at the site and offered similar comments previously!
Yes, embedding the videos in the block of text should work fine - just make sure you don't duplicate this in lightbox though, as this may cause some confusion for Googlebot.
I'm afraid I can't quite remember what the site looked like last time, but I have to say I actually think the overall look, feel and structure is pretty decent. Good job! My main concern generally speaking would be with the site build and the back-end. It's currently very slow to load and things like the drop-down don't work very well on tablets/mobile devices. As mentioned, the videos are also delivered through a lightbox in a slightly strange way which isn't great for SEO.
Video wise - I do completely take your point about the value of the content even though it's not ideal, however, I would advise extreme caution if you're serious about trying to rank with rich snippets. It's not easy to "undo" getting a video rich snippet - and if the poor quality thumb actually lowers your CTR and therefore rankings, it'll obviously be pretty disastrous for you. So, I definitely recommend split testing this if you can before pushing ahead - using SERP Turkey as a tool to do this for you.
