SidneyBlondellDecember 7, 2014
Pros
It's got a fancy name
Cons
It doesn't do anything
Summary
Another Microcrap monopolization attempt

tuan-buiNovember 7, 2013
Pros
absolutely none
Cons
this crap byproduct from microsoft still exist because of stupid netflix. it only lingers around like a dried up poop on a dog's behind. everytime i play a movie on netflix..."plugin-failure". numerous time uninstalling/reinstalling, countless ways of removing and installing. still the same crap. NETFLIX get your head out of your ass and ditch this crapware
Summary
Worse than Flash
CyberSkullSeptember 16, 2013
Pros
I need Silverlight to watch Netflix. Not really a pro.
Cons
Always invokes the discrete (high-end) graphics card on my MacBook, increasing head output needlessly and quickly quaffing my battery. Very inefficient even on the simplest of tasks.
Summary
Don't use it unless you have to.
On Netflix does not work properly - Microsoft crap

Pros
jerky picture most of the time -
Cons
jerky picture not synchronized with sound, resolved temporarily with removing silverlight from Library and reinstalling, but only temporary - MacBook Pro 1,2 Mac OS X 10.6.8 - true with both Firefox and Safari - it seems to screw up the whole web page rendering process, at least on Safari, even after one has stopped fustily trying to view Netflix. I have never written a review before. I wish there were negative stars.
Summary
gooooooooood

pietro3_dotmacFebruary 21, 2011
Pros
Functions automatically.
Cons
Still does not help with DRM.
Summary
A little bit better than flash, what concerns resources
McUsrJanuary 18, 2011
Pros
Streams media within brows with acceptable definition, at least from the site I use for streaming media.
Cons
Pity the sound control doesn't work properly in real-player
Summary
To me it is just a plugin like any other streaming plugin, except that it performs a tad better than the last production release of flash.
Not so great !
patrousDecember 17, 2010
Pros
It's free.
Cons
Have to reinstall it on a regular basis to be able to watch Netflix movie downloads as sound gets chopped up or image freezes and gets out of sink.
Summary
Doesn't support PPC Macs.
gmallingJuly 18, 2010
Pros
There are no pros for this product, it won't run on my PPC Mac.
Cons
CNET TechTracker persists in recommending Intel Mac only applications for my PPC Mac. BLEECH!!!
Summary
Useless on PPC Macs.
Worthless to Apple Power PC users
jdillinger_dotmacJuly 13, 2010
Pros
No cost program
Cons
Doesn't work on millions of Apple Power PC computers
Summary
Would be nice if they would alert you to platform requirements BEFORE you wasted the time to download and then have to erase the program.
