I would think the 14 channel you are missing are the 14 'NEW' xxx channels.
The 0.5 PVR client must have code in it which enters the pin code to unlock the 4 xxx channels which were there before these 14 'NEW' ones were added..... so the PVR client will need updating to show these new ones.
I was responding to the question on what the poster was seeing. There were some non-porn channels that were not previously detected by the PVR client as well, but eventually showed again. I can only speculate that the code automatically enters the pin code when the server requests one, but for some reason, most newly added adult channels do show, while the ones that previously did show aren't. I'm not griping, just observing what's happening. How much porn do we need, anyway?
