Thanks Gort, I'll try that. But will it mean switching settings on the TV/unplugging the RCA Cables every time I switch source?
I don't think you can re-assign rca inputs on your particular Samsung.
If I'm correct, the TV first appeared 2009, there's a firmware update from 2010.
The screen size is 1360x768 if I'm looking at the correct model, in which case set the humax resolution to 720p and not 1080i or 1080p
You may have to do a factory reset, default reset, without format and choose 720p on initial install for the 720p to stick, you'll lose your schedule list of programmes you want to record so take a note or picture with camera phone or similar.
let us know how you get on
