I have a Mac Mini that's a few years old.
I'd like to use it for watching online video, because it's small, we're not using it for anything else, it fits nicely under the TV, and I can connect its video output to the TV. We've got a month's free trial of Amazon Prime Video.
It's 32-bit (Intel Core Duo) so it's running Mac OS X Snow Leopard (version 10.6), which I understand is the most recent version of OS X that it's possible to upgrade it to. It has 1Gb of ram.
I've upgraded Flash and downloaded Silverlight and although APV videos won't play on Chrome, they will play on Firefox. Which is ok.
But when I play them back I get stuttering. š Sometimes it's ok for a minute or 2 and then we get a little stutter, other times its stuttering every 10 seconds. It seems to stutter mostly when there's a big change in the image and lots happening in the audio – that could be my imagination.
To give video playback the highest priority (the machine is not being used for anything else), I did a renice -20 pid
for the Firefox process and for the Silverlight process which it spawned. That didn't seem to help.
I know that the problem is with this machine (rather than with our internet connection or our router) because I've tried watching the videos on my laptop, connected to the internet in the same way, and that works well.
I've rebooted the machine and I've made sure there's only 1 logged-in user.
Can you suggest things I could try in order to make Amazon Prime Video play back without stuttering? Thanks!

My guess is that your CPU just isn't up to the task of decoding the stream of data that makes up the video stream for several reasons.
You can verify that the CPU is indeed the culprit by rebooting your Mac and opening only the Activity Monitor app and watching the CPU graph. Set the update interval to be 5 seconds in the app and then open your web browser of choice to an empty page. Again, let the CPU settle. Lastly, load the video you want and then pause the stream.
Looking at the CPU load at that point will let you know if any other process is hitting the CPU in a meaningful way. Anything over 5% would be worrisome from a maximum performance standpoint.
Then let the video play and watch the CPU allocation.
Knowing that the CPU is the problem, you can try reducing the screen resolution or putting the browser on an external display VGA or reducing the color depth of the main display might all help or hurt CPU load - so running some controlled tests might get you to acceptable settings. If not, you could get a secondhand iPod touch or iPhone/iPad and probably stream Amazon video inexpensively and far more smoothly than your Mac.
