Replay plugin remains at version/loading screen for extended period of time (3-4 minutes).

Later the actual replay app appears and starts replaying the audio at a very fast rate. Once it has caught up with itself it continued to live monitor at the correct rate.

Disable "Talk Talk Web filtering Anti Virus", in particular the "real-time scanning section" appeared to cause the problem.

Adding an exception to the list of the recorder IP address solved the problem.
