If you will be wanting HD or will be viewing on an HD set...I seriously recommend getting some aftermarket cable, with high quality sheilding.
The better the signal is when it gets to your digibox, the better it will be when it leaves.
Email this guy and ask him about some cable.

And I recommend plugging all your kit into one of these...thoroughly recommend
