Hi,
SCART works quite happily by 'daisy-chaining'.
most auxilary devices have an 'IN' and an 'OUT', so your DVD should have 2 SCART on it. plug the 'OUT' into the TV (I assume the samsung is a TV). and plug your existing connection into the DVD 'IN'
If this doesn't work for whatever reason, or your DVD doesn't have an 'IN' for throughput.
P.S. When I say daisy-chaining, most devices support running the SCART through each other, but you normally have to select AUX of some sort on the middle device you are streaming through.
