To be honest there are so many hosting companies out there it would be unfair to just pick one out just because a customer may have used them before.
Your best bet is to research how many companies there are in your price range and then compare your needs to the price of each company you found.
what i need to do, are as many websites, users and actors, actors can press from their page a "live stream" button and connect his webcam or external cam, and users sees what he acts.
from your experience, can you recommend web based live video streaming software works with PHP and wowza hosting to do what i want.
thanks for your help,
