My system: Dell Precision 380 Desktop, 6 Gig RAM, Ubuntu 14.04.

POL version: 4.2.8

I use PlayOnLinux to run Adobe Flash Player in Firefox under Wine because Comcast/Xfinity won't run on the regular FF browser. This is because the the most current version of Adobe Flash Player  available for FF on Linux is too old. Xfinity states: "The minimum required version of Flash for this video is 15.0.0.152. Your current version is 11.2.202."

In addition, Comcast/Xfinity won't run on Chrome because Chrome uses HTML5, not Adobe Flash. And, the PepperFlashPlugin can't seen to get past the Digital Rights Management at the Xfinity site.

Problem - Which program or programs should I set a higher "Process Priority" using System Tools > System Monitor: Should it be PlayOnLinux, or Firefox, or the Wine Server, or the Flash "Plugin-Container" or all of them, as each one is nested inside the previous program?

Update: I just tried the latest "freshplayerplugin" installed from PPA linked at: http://www.webupd8.org/2015/06/fresh-player-plugin-gets-hardware.html?m=1

Unfortunately, the freshplayerplugin caused FF to crash when playing any Flash content.

That is odd that it won't run on Chrome, because Chrome has Flash built-in (Chrome, as well as every other modern browser, can use Flash and HTML5 video elements.). 

Really, your best bet is to use the regular Linux version of FF, but since that version of Flash for Linux is no longer supported, you would have to use Chrome (pepperflash shouldn't have a problem with it). Chrome should fit the bill. What happens when you are trying to use Chrome on Linux to view their site? Does it work on Windows through the newest version of Chrome? If so, it should work on Linux the same way (they are similar enough to where HTML5 and DRM on Netflix's site works through Chrome without changing useragents).

Changing the process priority won't help; that is not what process priority is for. 

I've had some major problems with the newer Firefox in PlayOnLinux.  I used to be able to play Flash Facebook games and even Unity Web games, but now it crashes or locks up.
For example, the first time I tried Dead Frontier it ran perfectly, but this was on an older version of Firefox.

Now it doesn't run at all.  The only other solution I found was using Pipelight (which uses Wine Staging) to play Unity web games like Dead Frontier.  It works perfectly too.

@Ronin DUSETTE:

Tested 6/29/15 on newest version of Chrome.

1. I can't get any Xfinity "on-line streaming or on-demand" content (i.e. LiveTV, Movies, or TV Shows) to play on Chrome on Ubuntu. The videos never load (though previews will play).

2. Xfinity "on-line streaming and on-demand" content (i.e. LiveTV, Movies, and TV shows) will all play on Chrome and Firefox on Windows XP.

It seems that somehow, Xfinity/Comcast uses a form of DRM that will not allow videos to load once Ubuntu is involved (without jumping through all kinds of hoops). I'm glad I can use PlayOnLinux on Ubuntu to watch videos on Xfinity.

I'll have to do more research on how best to use the "process priority" as it made some, but not a lot of difference on how smoothly live video streams played.

1. Try using a user-agent switcher to tell chrome to tell Xfinity's website that it is Chrome on Windows. That may help. 

2. This is not Windows. ;)

The "process priority" is not going to help you. That is why it did not make that much of a difference. I am not entirely sure where you got that from, but my advice is to try and get it running natively for the best performance.
