I've done it using just a scart also, or possibly even just the normal coax cable and my cheapo Panasonic DVD recorder.
It's easy - pretty much just push play on the video and push the record button on the DVD and you're done.
It helps to have everything cabled up correctly, but it's pretty straight forward. The DVD doesn't know what it's recording - all it knows is to record 'channel whatever' or the signal from the scart interface. It doesn't know whether this is your home movies, RTE or whatever else is coming down the cable.
