My most used source is my Denon Blu-ray player, followed by my AppleTV which I use to stream Netflix and what TV shows I buy off of iTunes.
I do not have cable or a dish but I buy a lot of tv shows on DVD and movies on Blu-ray. That is why the above is so, however, when it comes to music the only source that I use is my Pro-Ject Xtension Turntable.
