Well, I tried it on my JU last night, and it did resume from the last place. Note that I tested it with files that did not require transcoding, as I doubt it would work with those. On that note, what profile do you have selected? If the profile you are using is forcing transcoding, that might be the issue. There is no K profile, so use the J profile.
