I have created a very simple flash movie player using Flex 3. It can be re-sized and it will play single flash movies(flv) by setting up a flashvar call vf.
There is an article in my Adobe AIR Diary ( see the Books menu) or go straight to the article here. I have made the player free to download and use if anyone is interested.

This was quite an interesting "home brew" project I put together over the weekend for my brother. He runs a small engineering firm and has a keen interest in both photography and railways. Add this to my curiosity with what can be done simply with Flex and you have the Video Jukebox.

He is currently building up an archive of photos and videos of railway related subjects for people to access on the internet. So I have created am embeddable video player (a widget to use the web 2.0 terminology) that can play the videos that are uploaded to his site. The list of videos is dynamic so as more are added to the site the available list will get longer. Still in the "Beta" stage at the moment (there you go web 2.0 again), you can see the player in the left hand column.
