I have a client who runs a small resort. Right now they have six DVD players that feed into two quad digital modulators. From there, the signal runs into their cable TV system. So basically they have 6 custom movie channels.

They want to ditch the DVD players and move to a computer system that way they don't have to worry about changing out the DVDs, scratched DVDs, constantly replacing dead DVD players, etc.

So I need to be able to get 6 channels from two computers into these modulators so they can feed into the TV system. These people I am working for are pretty cheap and aren't gonna want to spend a bunch of money. They want to do as much as they can with their current hardware which would be the modulators which only have composite jacks. But honestly, I will talk them into whatever is the best solution for this.

My first idea was to install three audio/video combo cards into each computer and then find a program that can manage sending a different movie to each channel, but I've been told this won't work. I've also been told that I should ditch the composite idea and look for an HDMI solution. My client currently has only composite hardware and we'd prefer to use that if we can.

So if anybody can recommend both a hardware and software solution for what I need to do, I would be most grateful. I appreciate any help.
