Yeah I have run into this, notably with the Xbox Live app for Windows, which totally saturates the line and generates something like 15% packet loss reports. However that's a different event to the occasional lower but prolonged packet loss which occurs infrequently and usually on a more idle line; which I believe to almost certainly be caused by something beyond my equipment. Knowing how OpenReach operate (who manage our largest internet infrastructure) it's a fairly safe assumption that it's a fault they've introduced somewhere.
