Thanks for your input. I have a few questions on what you said:

1. "You can set your server and the script up to cater for 1-2hr videos (if your server is powerful enough)"
By "powerful enough" do you mean enough disk space, or something else?

2. I understand that source code is not available, so how can someone modify the code for this script?

3. By "normal PayPal" does that mean it does NOT support Payments Pro, where the customer can do a credit card purchase directly on my site?

As for the price, I don't know if anything available will work for us, and I'd rather waste $10 than $400!

You said you're not on the script team, but do you work for the company?

I'm wondering if I can submit specs for changes that I would need, and get a quote and a promise of delivery.

thanks again
