@Hypopyon, If this were myself, I would run the auto test, example for a two hour movie scenario:
This test will run for 125 minutes, once every five minutes, testing upload and download minimum 1MB per test run, 'nfw' is selected to reserve bandwidth as were simply getting as close to a connectivity test as we can. (This means the tests will not forward to a larger test size until the test takes seven seconds.
Although I'm not up on the TTL (how long the test server will wait for a response before giving up) therefore the two hour test every five minutes, if your getting eight droputs per movie, you should catch several, in theory.
Though in your case, I might be running wireshark , (packet capture) to view the responses during the loss, which can be a bit overwhelming to learn.
