watching a recording delayed and I see 2 problems. first, it does not know the length that has been recorded so far. after letting it play, the scrubber over time gets more time added to it. this makes it impossible to fast forward to minute 10 right away. let it buffer up while playing and you can eventually do it. the buffer really takes a long time to catch up if you're way behind. this is what I have to do to change devices/rooms and pick up where I left off. all of this is before the recording is finished.
Second, when I start playing from the beginning of the recording, then there is a problem when you're ready to fast forward the very first time. when you click the right button, it moves to where the end of the buffer is, not from the point of where the current position is. therefore I have to rewind back to where that point was and start from there. once I do that it works fine.. so I have learned to take note the first time where I am.
