did a quick test on how PVR behaves after this. Jump forward/back still don't work (which was expected).

I'm not entirely sure about FFW/FRW, which AFAIK is atm the only reliable way to "skip" in the timeshift buffer of backends using XBMCs demuxer. It's kinda still working, but I think not as reliable as before. But I can't really tell because I'm not using PVR in XBMC due to missing stepforward/-back which is essential for me. So I only did a quick test, and sometimes it worked, sometimes it was caught in some sort of loop. The loop looked like this: I started ffw, and at a fixed position it jumped to the beginning of the timeshift buffer and started all over again. The jump occured somewhere in the middle of the buffer - so for sure not at the end. Will compare to earlier behavior later and report again if the issue wasn't there.

ffwd/frwd work fine for blurays, but are for sure broken now for PVR addons using XBMCs demuxer. At least it didn't work at all for me now (XBMC always tried to ffwd/frwd at the end position of the buffer). Also step forward/back now jumped to the end of the buffer instead of the beginning like it did a few hours ago with the same XBMC version/install which is kinda odd. It probably depends on how far the TV show already progressed when you start watching it - that's at least the only explanation I can think of atm.

@da-anda which backend? and there is at least one bug in that code when no epg tag is present for the channel or when the epg tag changed.

Lars Op den Kamp

oh nvm, you're talking about xbmc's demuxer, not one in the add-on
