The broadcast versions will always be sharper/more detailed as they were broadcast and captured in native PAL 16:9 (1024x576) where as DJs LD captures are coming from a letter-boxed NTSC 4:3 (640x480) source, which roughly speaking gives the broadcast versions ~37.5% more resolution. That said I was pleasantly surprised by the picture quality of DJs capture! There was some block like noise I could see but this may just be from the H.264 compression...?

As someone who has done a LD preservation of the 97SE myself I am curious to know what AviSynth filters you are using? :)
