[Cable] Streaming Videos Causes Internet Downloads to Slow / Dro
This is perhaps more of a computer / lan issue than it is service.
I have 25 / 2 cable and a E1200 router running DD-WRT.
It seems that whenever I start to stream a video (generally flash based), my ongoing downloads experience an immediate and sustained drop in speed until I stop the video. The connection is far from saturated when this happens.
For e.g. I have a 400 kB/s transfer (purposely throttled) @ the moment in a download manager. If I load up a CNBC or CBC video in any browser, that transfer will drop to below 100 kB/s for as long as I run the video, after which it will immediately go back up to the throttled level.
Again, multiple speed tests verify that I have plenty of unused throughput in the internet connection.
I have no special router settings, e.g. QOS, no software firewall and no other special programs running on the Win 7 machine. I have the latest versions of Chrome and IE and latest Flash.

You can rule out the router by plugging your modem directly into your computer.
How are you throttling the download?

Yeah, sounds like a local issue (could be a number of things).
I know this sounds so obvious, but have you tried updating your NIC drivers to the latest from the actual NIC manufacturer?
Don't know what kind of system you are running, but things like this can happen when the CPU is taxed by Flash to the point where the NIC interrupts are not properly attended to (you could try disabling "Interrupt Moderation" for you NIC? ...but often the drivers themselves are the problem).
