When ever I watch any video it starts and stops (long or short). Was having trouble with both IE*,FF18.0.1 in that they would not load pages (took 2-5 min a page). Now that is OK.Maybe I screwed up some thing fixing that problem.I have done a few speed tests (have FIOS) AT SPEEDTEST.NET and others AND d/l 19.6, u/l 4.63. Below is sys info,not sure if its what you might need.
