Hi danant,
The old pace boxes used a special IRDA standard for their remote controls which meant that normal remote extenders wouldn't work with them. (However, I think some of the 4xxx series are different.)
The Samsung on the other hand uses normal infrared so it can be controlled using any of the remote extenders you can buy from places like Maplins or Tesco.
Hope this helps.

to cableforum too.
Phil.
