Hi,
Get a Panasonic DVD recorder with hard drive they have a button which is called EXT Link which you press and it automatically records the prog your Freesat unit is on.
Press EXT Link button again and it will stop recording.
Providing yor scart lead is on AV2 and you set it to link one in the menu it will go to AV2 and record as I said previously.
Hope this answers your question???
Brian.
