I'm British and I get the region 2 DVDs, but I CAN say that these episodes, while not being the best of the seasons, are a welcome return to the season one stories. Although many think that season four is the weakest, while I agree to a degree, Farscape still remains as the best written, best acted SF show on telly.
And to that guy who thinks that A Prefect Murder is edited wrongly by ADV, maybe he should watch the episode again. The first four scenes are repeated over and over for the first ten minutes of the show from the different character's perspectives. It's an artistic thing, a different way to tell a story, it's EXPERIMENTAL, and it's one of the reasons why I love the damn show.
