Already posted this to the super8 thread but moving it over here where it's a bit more on-topic - here's how ld-decode compares with the X0 project capture:

ld-decode has more noise and comb filter aliasing, but considering the source player is a repackaged cld-s104 (v2800) and the total equipment cost, not too bad.
edit: Made a version with some NR (0.25IRE chroma, 0.7IRE luma). Still not a match for the X0, but a bit closer - http://screenshotcomparison.com/comparison/128842
And one more with Chroma LPF, which closes the gap on C3P0's hand etc http://screenshotcomparison.com/comparison/128845
