I just finished testing v0-110 on both my FireTV Stick 4K and Shield TV 
on a recording in progress. It performs the same on both. Both pause for 
about a second as it passes the "end time" set when the viewing started 
or fast forward or rewind was last pressed. It audio pause is longer for 
my Shield TV because the audio is sent from the TV to AV Receiver bia 
SPDIF optical cable. The audio always does that on any pausing on any 
app on the Shield TV. FireTV stick 4K has the same audio pause as the video.

This works well for most practical uses of this feature in my mind. What 
I do in testing is more extreme to try to break it.  A valid use case is 
starting a recording of a morning new show before you get up and then 
playing it 30-60 minutes into it. I would skip commercials in this case 
but once you reach the real current time, then you just watch and no 
more attempts to FF.

I tested this aspect on the Shield TV and found an issue. I started 
watching at the beginning and saw the "End time" was 38 minutes into a 
60 minute show. I used the down arrow to skip until 30 minutes and the 
right arrow to skip 1 minute at a time until I hit the current real 
time. I tried to skip past that but you'd see a few second skip and that 
was it.

So I let it play and a few seconds later it paused and didn't continue.  
I hit select and the OSD popped up and I could see the play time greater 
than the end time, but no -- for the end time. I moved the cursor around 
until it was on "play" and when I hit select it started at the very 
beginning of the recording.

Let me know if you need anything else tested.
