  1. Why have you written more about some decoders than others?
    Firstly, there's not much to say about the ones that are perfect! ("Perfect" or "faultless" on these pages always means "perfect in terms of these tests" - they might look terrible, cost too much etc!). Secondly, an obscure decoder that doesn't work well really just requires a "Look, it doesn't work, don't use it!" while a very popular decoder that has some problems needs those problems pointing out in detail, since lots of people are using it and will question if or why they should switch.
  2. Another question....
    Each test has its own FAQ section, and there is also a general FAQ. Please see those.
