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.
"PAL" 16:9 broadcasts are only 720x576, as they're anamorphic.
By my reckoning, there's 60% (1.6x) more vertical detail in anamorphic PAL than 4:3 NTSC (432 lines of active picture against 270).
