Hi I might be wrong but I think "smart link" is unique to sony products.
I have a sony tv and video, smartlink works no problem but when I try to use it through HDD recorder which is a different make it doesnt work. the smartlink is built into the sony VCRS,. HDD/dvdrw recorders and I think your tv if it says smartlink capable it means that it will communicate with a sony VRC/dvdrw/hhd recorder with built in smartlink
Google it and see
hope this helps
