I'm having the same issue. I have Krypton installed on a Raspberry PI 2 and Firestick. Neither of these give me the option to resume a recording from where I left off. I've also got Jarvis running on a windows 7 machine. The resume function works perfectly there. They are all talking to the same backend.

Also, I have Windows Media Center and ServerWMC running on another instance. I have exactly the same symptoms with PVR.WMC - no resume capability in Krypton, works fine in Jarvis.

Hurts the WAF big time...

So it seems the root cause isn t the backend or addon. And the issue exists only with RPI. It could be a cast issue or unaligned issue of the integer value passed by kodi to the addon.
Have you placed a post in kodi thread about this problem ?
