I personally welcome the competition in online video rental, especially here in the UK where there is a very limited choice.<p>I think if YouTube can nail video quality and streaming reliability then they could seriously threaten the likes of iTunes and NetFlix. Hopefully they will integrate a simple/low friction payment mechanism, and focus on one-off movie rentals, rather than having to sign up for a subscription. If they can do this then I will be very keen to use this service.
