With build 412, it seems that whatever is in recorded TV when I boot is shown, but if something is recorded during the session, it does not show until I reboot. Reverted to 411 to check this and if it is stable for a day or two, I will update again to confirm.

Not many changes in 412. Only "Added: PR:6937: [epg] start epg container asynchronously" sounds like a potential culprit (although I'm unsure of the connection between EPG and recordings).
Let us know if you are sure 412 causes a problem.

Yeah, the fact that I am seeing TV problems in a build where there is specifically a TV related change seems significant. I haven't seen the problem before, but I was able to reproduce it at will this evening with the MediaPortal front-end. Had to reboot in order to watch a recording.

I will definitely keep an eye on this.

I'm not seeing this behavior with 0412. I use the pvr.mythtv plugin with a MythTV 0.27 backend. I installed 0412 last night and the overnight some shows recorded and show up. 0412 has been booted ~22 hours now. My EPG on liveTV also appears to be updating correctly and the program listed appears to be the one actually on when I spot checked.
