Hello every one, I am working on a project to create a the ultimate MAC DVR. We are looking to capture 3 seperate channels at the same time off a cable (we need to record the news on all our local news stations) Seems like there are not many people doing this, well I can't be sure, but the companies I have tried thus far have seem confused when I asked about mutiple units recording at once. We need decent quality, not awesome, but good. We'll worry about HD in a couple of years. The software we use to schedule will also need to be able to handle 3 units scheduling. While money is always limited we have been granted a reasonable amount to do this project. Please also list the specs you on the power mac you would purchase to do this. Thanks for your help on this.
