I have a video source that gets encoded at 4mbits using a tv tuner at a remote site. It gets recorded to mpg files on the hard drive.

At another site, we have a computer that plays them back and between the sites we have a 4mbit connection.

If a video file is recorded between 1.00 and 1.30, it then starts getting transfered using a folder sync program at 1.30 and will finish transfering at 2am. So it takes the length of recording to transfer. This means a 1hr recording will take 1hr to transfer.

What I am wondering is if there is any program that will be able to transfer the file as it is being written to the hard drive at site A, and send it over the network to site B. That way it can start transfering 1 min after the recording starts and be at the other site around 1 min after the recording finishes?

I noticed I could use windows explorer and copy the file and paste it to the shared drive and it will copy all that has been recorded up untill i pasted it, but it is still recording when i do this and doesnt wait for the rest - it just copies up to when i pressed ctrl + c - and the partial file is playable up to that point also

I have thought about breaking the recordings into smaller pieces but the recording scheduler takes 1 min from the end of a recording before it will start the next so its a bit too much.
