I'm looking for a single dvd player that has a repeat button on the front panel. This machine is for a museum exhibit and must continuously repeat the 16 minute dvd program. I have an RCA now that has a repeat function but everytime it is powered down it loses the programability and needs to be programmed again the next time it is turned on. Not a good option for older volunteers whose vcrs still blink "12:00" all day long. Any model numbers out there??
