How to obtain proper aspect ratios for sequences in Premiere Pro?

Question

I'm posting it here, because I use AE SDK for the effect.
I've got a RED sequence in Premiere that is 2048x1152. The footage is 2816x2304 anamorphic 2:1. The sequence preview is 1920x1080, like any Premiere preset over HD. I can't seem to get the proper size and aspect ratio to resize the UI controls and position the effect.
Normally I'd use this:
scale_x *= (PF_FpShort) in_data->pixel_aspect_ratio.den / (PF_FpShort) in_data->pixel_aspect_ratio.num;
scale_x *= (PF_FpShort) in_data->downsample_x.num / (PF_FpShort) in_data->downsample_x.den;
scale_y *= (PF_FpShort) in_data->downsample_y.num / (PF_FpShort) in_data->downsample_y.den;
But in this case it doesn't seem to work. Also standard procedures for UI resizing from SDK examples fail.
How can I obtain the proper aspect ratio and sizes?
Thanks in advance.

Premiere Pro is not well designed for this type of collaborative work flow.  That's not to say something can't be made to work, just that it may not be as seamless as you'd like.
For starters, there's no way to really 'merge' the changes made by two different people working on the same project, so one of the primary rules you'll have to implement is that only one person at a time can work on any given project, and you'll have to be in constant communication as to who is working on which project, with person A leaving it alone until person B gives the go-ahead.  At which point B will have to leave it alone until A gives the go-ahead.  If you don't do this, your changes will overwrite each other and you'll get nowhere.
Second thing to be aware of is that clip markers are stored with the media, so while sending only the project file back and forth is fine for most things, it won't work with clip markers.  You'll also need to transfer whatever media files have the markers.  Given the relatively large size of media compared to project files, it may be best to simply forgo using clip makers.
If the hard drive setup is not identical on both machines, you may have to relink the media with every swap of project files.
