See to me Exporting Video out of Sonar is a waste. 

In general, I agree with this... there have only been a handful of times I've needed to export video from Sonar.  It's handy when you want a one-click function to spit out a rough cut, but I've only needed it to send a preview to someone not related to the project itself.  The people close to the project would already have the video available, so for them a wav file is preferable.  Video export, as a result, is only tangentially related to my workflow.  Other people might have more valid, pressing needs for it, and that's fine.  
 
As an aside, I think I've done a poor job of articulating my specific agenda or desires in the other threads recently.  I don't care about Mac, or Cakewalk's business plans, or any other modifications to the app or plugins or whatever else.  The rest of the application is so incredibly polished, there are only a few minor tweaks I would suggest for it.  Trivial stuff.  So perhaps I should be giving them more pats on the back for a job well done in the track view, synth handling, envelopes, the list goes on.  Stuff that other DAWs either don't have at all or handle very poorly.  

All I want is the staff view to be on par (or somewhere, anywhere, close) to the rest of the application from a functionality standpoint.  I was trying to think back to the last time the staff view had an honest-to-god upgrade in functionality.  I remember using Sonar 2.2 -- the first version I used -- and it was almost identical to what we have today.  
 
So people are now mentioning how "some people just like to complain, they can never be happy, it's how they are," etc. etc.  I'm very happy with the rest of the app.  I continue to pay for it.  But to blindly cheerlead and not make our wishes known doesn't help the application.  It's like living in an apartment where the A/C unit has been limping along, barely keeping the house cool for years.  You tell the landlord every so often, but every month they show up and upgrade the refrigerator.
 
They say they hear us, and that staff view improvements are in the backlog.  They've made a few bug fixes here and there in the staff view over the past 18 months, gotta give them credit for that (though I must admit I'd never run into any of the bugs they fixed).  I keep hoping we'll see a real, solid push at some point to bring it up to date.

As mentioned above by JF,  the video support is not an issue.  If you seriously score to picture you should have the tools and knowledge to work in Sonar without a problem.  In fact, I would suggest following his workflow for any DAW.  The are just two many different types of files/codecs and other issues that come up day to day.  I would not want a DAW that wasted resources on Picture issues like editing and such.  There are so many apps that specialize and do that just fine.  
 
When you are being paid to score to picture,  you are usually under very tight deadlines and there is a ton of pressure to work fast and efficient.  There is no other DAW, in my experience, that has handled rendering and plug ins and now mixing as well as SONAR.  If SONAR polishes up notation, adds rippling, goes Mac......no reason whatsoever to not use it.  It would just be so far ahead of every other DAW.
 

While I've done less scoring to picture than I have multi-cam live music production (something I have thousands of hours of experience with).
I use Premiere Pro CS6.  It isn't a lightweight tool and I wouldn't expect Sonar to have that kind of functionality.
 
I will say that there are problems exporting a WAV out of Sonar and importing it into Premiere Pro and having things line up like they should.  Typically a small adjustment needs to be made if putting it right back to the exact same source material.
 
I've personally gotten used to just doing the audio in Sonar, then import that into Premiere pro and line it up there.  
 
For much more basic projects, I think Sonar should have a bit more capability to import any modern video, add/create audio for it and export it in a usable high quality format.  Setting the start and end points of the product.  Simple as that, and today, my experience suggests that can't be done.  
 
Maybe I'm doing something wrong, but I've seen others post the same things.
