Media Player and Encoder

I'd like to build a GUI program with VB .NET. It would do the following:

I have three separate computers that have video capture cards on them. I'd like to have a VB program on a fourth computer that can simultaneously connect to them and have them start capturing with Windows Media Encoder all with a press of a button. So for each computer it'd have to connect through ethernet, command it to record at the correct settings, and then save the file.

Then once I've captured video, I'd be able to play those captured videos back on windows media player by pressing a button on my GUI again.

Does this sound possible?
