Yes the current Flash file looks fine on the site.
The problem, as I understand it, is that if you buy the file you get the mini file that is on the site (Flash), which is iPhone size, so if 'fullscreened' it looks grainy. He would like the purchaser to get a full size video.
Something in the system is being missed (like the actual file download location being wrong and linking to swf file), or a workaround is needed.
Not sure if this system allows a custom download location or if he needs to figure a way around it.
I never work with wordpress .. unless I'm forced to.

I do not work here, but the benefits are still awesome
