I converted a full length DVD movie to the new iPad acceptable .mp4 format, these files are saved on my desktop downstairs, but I wanna watch them at my bedroom, Can you manage to do that with some kind of help?

Sure you can do that with the help of Pavtube Streaming Server. It is a Video Streaming Server product that can stream any audio and video files from your PC to Android, Windows and iOS devices, letting you play local video to Android tablets, smartphones, Windows slabs, etc over wireless network. I have a guide page can show you how to do that.
