2 -> Sorry what is "play spot" ? (i know my english is very bad . Sorry for the inconvenience)

The resume spot that is saved when you STOP a recording but don't finish it.

The addon handles them using internal bookmarks of XBMC. It is preferable because XBMC use time position instead framecount.
The old addon uses mythfrontend bookmarks stored in backend. But like EDL we had to estimate the framecount before to store them and then do the reverse operation to retreive them with an approximative error depending of framerate precision.
So here i prefered to use XBMC features. Trying to play a recording for few minutes then stop it. On next play XBMC will propose to start at your previous spot.

I see the reason why you have made this decision, but I would suggest that as this is a MythTV client, the mythfrontend bookmarks are a better solution.

The reason being that MythTV is a system that can have multiple frontends that run on various platforms. With the cmyth addon I can start watching something on my real mythfrontend in the lounge, stop it and continue from the same spot on my xbmc mythfrontend in the bedroom.

Having said that, this is the desired functionality in my household. For a house where multiple people are watching the same show from different frontends, you wouldn't want a single bookmark, so the xbmc feature would actually work better.

I suppose what would be ideal would be a setting to choose the server bookmarks or the xbmc feature??

Either way I won't lose any sleep over the few times I start watching something in one room and finish in the other.

Thanks
Ben
