[mythtv-users] Toggling compositing

[Chris]

Hello Everyone,

I have very naive newby question.

When I setup my MythTV frontend I was having some trouble with tearing.  
I originally had the video playback profile set at Normal and I read 
somewhere that what I really wanted was VDPAU so I started messing 
around with the settings but couldn't get it to work at first. (For the 
record the GPU is GeForce 8200/integrated/SSE2 and the CPU is AMD 
Athlon(tm) Dual Core Processor 4850e × 2). The MythTV Official Wiki had 
a few suggestions one being to place the following in my /etc/X11/xorg.conf:

   Section "Extensions"
        Option "Composite" "Disable"
    EndSection

I think this was already in my xorg.conf  because it's there now and I 
don't remember putting it in (but that's another story).

The problem is, I have recently downloaded the Netflix app onto my 
computer and it wants compositing enabled.  So I looked for solutions 
and I found that I have a package on my computer called 
plasma-widget-toggle-compositing which looks like it might do the 
trick.  My question is:

If I enable this widget is it going to screw-up Mythtv somehow (Synaptic 
Package Manager suggests it is linked to file associated with Mythtv)?

My guess is no; but, I have had so much trouble getting this thing to 
work and wasted so much time fixing mistakes that I really want to avoid 
them.

Other possibly relevant information is that I'm using Mythtv 0.26 run on 
Ubuntu 12.04.

Thank you once again for your help and guidance.
Chris
