.NET Stream Media Player

Language:C# or VB.NET are fine. I prefer to use .NET framework 2.0 but if it needs use 4.0 that's fine. I don't accept 4.5 because there are too few people have .NET Framework 4.5. I need a application which can play video files from web streaming.(I will have some video files on web hosting, the application need to play these.) But the must important thing is the video files cannot save to hard drive. And it needs a pretty user interface. I will create 3 milestones(1/3,1/3,1/3),first one will release when the application is done(send me the bin). I will do some test with many computers see if it works. after that the second will release. After you send me the source code and I check it I will release the final. I need a .NET coder who is trusted and fast,I have many jobs to [login to view URL] is just a start. So although my budget is not much,this is only the small part of my whole project. if anything is smooth I will hire you again. If you can tell me how to protect the video files don't get stolen I will be happy. Please tell me the plan and which component you will use in PM.(no PM I will ignore you.) DO NOT write skype or email in PM.I only want to use PM here. I will not do any business outside this website. I am not good at English,hope you can understand what I want. Thanks! PS. Last time I tried to find someone to write a player which can play byte array and got failed. If you are able to write this please tell me.
