Noisy originals are difficult for any encoder - especially the single pass
encoders in standalone recorders. The encoder can't differentiate between
noise and image, and wastes bandwidth encoding the noise, resulting in "bit
starvation" - so much is wasted rendering the noise that there is little
left for the actual image.
I've read comments, but have been unable to find technical documentation,
that the new generation Panasonic "DIGA" machines run 3 encode strategies
simultaneously, and have an algorithm to pick the best result in real time.
Also they offer a long play mode having double the resolution of competing
decks (but there's no such thing as a free lunch, and you have to wonder
what the downside of this is ... more MPEG artifacts?). Your results may vary.
