Either you fixed the problem or my fellow curmudgeons need to upgrade their Firefox because your site came up on Firefox 3 just fine. Yes, the video was frequently interrupted for buffering. Try making it a smaller size (640X480, for example).
I take it that you aren`t in production yet? If you are shopping for partners you should include more technical details. And photos without "PROTOTYPE" plastered all over the product, obscuring it altogether.
I would want to know, for example, what is the drive? Hydraulic, geared motor, direct drive? Is there a "reverse" so that you could ramp it fully loaded into a minivan? What is the top speed and GVW? How long at Gross Weight will it run before needing a recharge?
Don`t answer here, but contact me directly because I can think of another market for your product.
