Thank you Eric,
you have cleared this Native Resolution/Double Scaling mess up with your post.
So as a conclusion to this, please correct me if i'm wrong...the only way to get a 1080i input signal with NO double scaling is going thru DVI with a external processor.
Will i still need the 5004 card if an external video processor is connected with cable/dish box source (HDCP 1080i)?1.b)
how do i tell the native resolutions of the cable/dish box? since they are output res configurable, i assume they themselves has a scalar/deinterlacer which i would want to bypass for the external processor.2.a)
DVDO vp20 supports 1366
x768. will i get 1:1 in this mode?2.b)
DVDO vp20 supports 1360
x768. will i get unlit columns in this 1:1 mode?
Thanks guys for this wonderful source of information. i almost pulled the trigger on dvdo+50ph9uk purchase.

I would like to point out from the start, that I am completely neutral on the subject. I have nothing to gain either way. In fact I have more to gain if it worked at the native rate than not. Since it is a cost effective solution.
I can tell you that they were very very evasive on this issue. It is obviously a very sensitive issue with them! The were running around the subject matter and blaming Pioneer where they could. I literally had to ask him to be straight with me and quit dancing around the subject matter.
The facts are that the key Digital in combination with the PDP-507CMX is limited to a 1280x720 scan rate. Regardless of whos fault it is. I really do not care!
He also confirmted that Pioneer panel will then scale a second time in order to fill the screen up to 1365x768. Otherwise you would have an image less than the full screen.
To make this absolutly clear, he did confirm that there is double scaling going on with this solution.
Now to be fair to Key Digital, there are many good reports on the picture quality with this solution. But I think I can do better with an external video processor.
My only concern is the proper support for HDCP using the Pioneer 2003 or 2004 card if necessary. I have my HTPC Connected to the 507 now, and it looks great at the native rate. But I have not yet tested the Scientific Atlanta HD-DVR or my X-Box 360 with HD-DVD yet. So I do not have a complete solution.
But I do not think the Key Digital is the best solution here unless you need integrated support without an external box. Or if there are HDCP issues that arise from external boxes.
I hope that clears things up a little.
