Hmmm... sounds an interesting telly! The "comb effect" definitely shows it's interlacing. I've not come across a telly that will automatically interlace non-interlaced video before - although I have seen one that refuses to sync to the SAM - a bit of a dodgy widescreen 26" CRT! Now the question is, depending how the TV is interlacing the frames, and how many frames there's been since the SAM was powered up - when the 'Interlaced Pictures' from FRED are loaded the frames might show with the intended 'interlacing', or be reversed - if 'A' is the frame with the top row, 'B' is the frame with the row to be shown below, your telly could interlace correctly so the TV displays with the lines ordered ABABAB, or could be out of order and display BABABA....
