Actually there is not much to say about it, it has a medion harddiskrecorder (german manufacturer) which had a dv link, the camera (I use an older mini dv cam) is linked directly to it through a 4-4pin firewire cable. Then there is a small tv which is connected to the medion recorder and that's it. Using the Medions set up menu you can select the camera and then select recording, the medion then sends the cameras image directly to the tv. On top of the tv screen there is the possibility to see the recording data which the medion provides. I always leave that visible so you can clearly see that it is recording, that information won't be recorderd to the harddisk but it just a small information stripe on top.
The only thing you see from outside the box is the tv screen and the camera's lens. For the future we are going to see if we can manage the same but with some kind of recording button outside the box, meaning the guests have to press and hold it and during that time it records, in that way I don't have to edit anymore afterwards which will be a big timesaver.
Now I just scroll inside the medion and cut the biggest parts (usually in the beginning of the evening) when nobody was infront of the box, the medion has some limited cutting and deleting capabilities. What's left over I capture to a pc and edit. for the capturing part I use use my sony vx2100 between the medion and my pc to send the images.

One important issue we discovered was that at the end of teh recording the medion has to be shutdown using the remote control, if the power would be interupted during recording the medion looses its data. For that case I give the remote control to the wedding couple and explain how they have to stop the recording, the data on top of the tv screen also shows them that the recording stopped.
