I'm designing a recording system for a hospital that will have 5 simultaneous composite video sources. I will record to 5 seperate hard disk drives (Firestore, etc) or possibly DVD recorders so they can edit after the procedures. How can I provide timecode to all HDD's / DVD's? Any help would be greatly appreciated...I'd like to know of other formats or techniques that may work better in this application (no tape though)....must be very user-friendly!!THANKS!
