Yes, the problem is twofold I think. First, USB flash memory, when compared to DVD media is quite expensive. Here in the states, even low capacity flash memory purchased in bulk are a couple bucks each. The other issue is that almost everyone has a DVD player and these days almost everyone has a BluRay player if they live in an urban area in the USA and have some sort of cable or dish type television service. Not all current televisions in circulation here are capable of using USB devices to play mp4 shows. As David mentioned, we are probably still a few years away from having the public aware of alternative methods of media presentation. Some day in the near future we may have DVD/BluRay players which also have USB ports and that will make it much easier for the public to accept the alternative ways. Right now, to use a USB device on my television, I have to get my flashlight (beamer) to see the USB port on the side of the large screen. Then I have to choose from a menu the proper selection to play it. With my BluRay/DVD player, I just insert the media and it automatically plays without any intervention from the user. When I want to watch a movie, I go to the nearest video store or machine and rent a DVD or BluRay - not a USB device containing a movie. I think familiarity is part of the issue with presenting shows on alternative media. Best regards, Lin
