To be more specific. You will need one of the ViP series receivers (dunno why DVR was even brought into this, lol) and either a wing dish to hit either the 129 or 61.5 sats (depending on your location). Instead of a wing dish you can get a 1000.x dish for a single dish solution.
Just going to give people a heads up. Top chef is now listed in the guide as "Top Chef: Las Vegas" so your old timers won't catch it. Also episode 1 is not listed as new so it may miss as well if you select only to record new episodes.
An OS and browser is a BROAD term. The 622/722 both have an OS and browser. How do you think you "browse" the dish online movies? The xbox 360 does not have a web browser yet it can stream netflix... To answer the original question though, no Dish receiver has the necessary software to stream...
Wow, not to rain on anyones parade, but you could not pay me to run norton 360, Trend micro, or Mcafee... They use so many resources and try to take over your computer, it is horrible. I suggest NOD 32
