We have a *really* old UHF decoder, the model I belive is Videocrypt IRD1S, its a black box.

Our setup has the Aerial cable going to the decoder, to the VHS and then to the TV - we are not using the Scart output (and so to use sky we tune a TV channel into it)

Our TV only accepts composite cable.

Is there any reason to upgrade? It works ok, the channels are scrambled for a few secs before the picture shows... I don't know if that is any different with more modern equipment. With a scart connection would we view sky via AV1 (or AV2) rather than tuning a channel to it?

And will sky charge $40 to do so?

Cheers
