Needs an update for 2.5.2

There was some complaint in another thread that this needs an update for 2.5.2.

I tried it with 2.5.1 before and I also had some issue on edit_product.inc.php.

Not working on 2.5.2 error when trying to create new product

I like the youTube demo, but wonder if it could be made into an embedded link so the video would play on the LiteCart page instead of off at youTube where they will do their best to suck potential LC new customers into somewhere else on youTube.  And they are experts at that.
