So all we have to do is to find someone who recorded this broadcast and we will have a HQ 97 SE ROTJ!

Any ideas who could have this recording?

I believe that the problem was that the processes in those days to capture digital broadcasts usually caused heavy smearing; however, recently someone did suggest that the smearing was inherent to the 1997 Telecine.

If the first theory is correct and the broadcast you pointed out is recent enough, then there is a possibility that we could find a recording with no smearing, which would be utterly fantastic. Good luck trying to find someone though. In the years this forum has been active, not many digital broadcast recordings have surfaced and all with the smearing, so it may be pretty hard to find a high quality recording...
