Thereby if you have the TV decoder on ( the button glows green and the channel is displayed ) IT WILL suck the life out of your computer connection -- in relation to download abilities.
FYI - for me - WITH wife watching weepy movie on HBO - download only up to 200 kB/s. Switched OFF I get 600 kB/s.
To make BitTorrent in particular - more efficient. From the OPTIONS tab
Go to Preferences - Connections ..Set max upload speed to 10.
Set Download speed to 0 ( unlimited )
Go to Bit Torrent - Set your connections and peers to 1,000,000. Upload choose low like 100
Additional Bit Torrent Features - check every box BUT NOT limit bandwidth
Protocol Encryption - Enable
The rest is just set to default.
Those are my settings and I get the max out of my connection.
The fact that NowTV uses your internet connection is obvious - they state so when you sign up, and it's the reason why a 6Mb connection is the minimum requirement for NowTV, as then you get 3Mb for the internet and 3Mb for NowTV, otherwise NowTV would saturate your available bandwidth (in my first building, it was an old one that could only handle 3Mb so no NowTV for us back then).
I'm curious as to how much bandwidth NowTV HD requires though. I plan to upgrade soon so hopefully the net connection can upgrade too to handle that.
Cable TV on the other hand - of course it should have absolutely no impact on your PCCW ADSL connection. Why would it. Completely different systems. It would impact you if you were using iCable for your internet though...
iCable on the other hand, might, if it's anything like cable in the UK which I can only guess.
In the UK, Virgin/Telewest/NTL cable customers get their cable and internet through the same cable. So obviously the TV use has an affect on the bandwidth in some minor way, as they're both digitial signals going through the same cable. If it works like that with iCable too or not, I don't know.
