Aequitas, is it possible to post and play HD videos only?
As of now the answer is no, however I'll dig a little deeper into the Youtube API and try and determine if they have the ability to sort or tear out HD videos only and work something in if its possible.
@Aequitas As much time and energy as you have put into this so far, might it make sense to make it work with WPMU where people are willing to pay a lot more for a plug in? Hell, there are private support forums that run $50 a month for MU. And the video plug in by Automattic isn't really a plug in, it's more like a development framework. Just a thought, really.
Your correct and I'm sure I'll advance it over to WPMU in a little bit but I'm going to have to find another hosting account to properly test it with WPMU.
My current accounts don't allow wildcard subdomain creation so its really hard to test out everything it can do when used under WPMU, I can get the basics of WPMU to run under my accounts but nonetheless I think the main reason why I haven't begun work on a WPMU advancement yet is because I gotta find a proper hosting account to test it under first.
