Yep, the channel requires a login. I'll share it later if we will not find a solution in logs.
Here is new PHT logs: http://pastebin.com/JvbBdvtb - looks like PHT trying to play episode when I'm tapping on it (instead of showing info, or instead of playing from provided PartObject)
And I have another question - is it possible to tell Plex/iOS that transcoding is not needed (the video is already marked as H264/AAC/MP4, but Plex/iOS still trying to run transcoding)?
