I'm sorry but that thread is very... old.
The situation in the thread is no longer, XBMC 12.1 can do the Crop Black Bars with DXVA.
Actually... if I do get a line at the right of the picture when XBMC does Crop with DXVA it already means the crop is now supported, and that I'm having a error when it is done.
I'm sorry but I feel sort of sad as I posted looking forward in getting some help with the problem... and well, the first reply I get seems to be from someone that only read the title and googled it, without further reading the description of the error or even acknowledging what was in both threads, this and the above linked one.
I already googled 'xbmc dxva "crop black bars"', 'xbmc black bars', 'xbmc zoom dxva', and performed similar searches inside the forum and the bug tracker. And all the results I managed to find are, just as the linked one, threads from a period where crop black bars was not supported along with dxva. Wich doesn't seem the case for sometime.

I was just responding to your call "Anyone knows a work around for this or is it a known bug or something" and nothing was posted... and the statement "or if my newbiness prevents me from doing a good search :3)" I simply suggested what you clearly already knew that a Google search is fairly comprehensive. (from the first message this wasn't clear).
I went to the effort of finding a video that had side black bars....(before I posted) with DXVA on the crop black bars had no effect, with software rendering it worked as expected and the black bars were hidden. I do remember someone in a thread in the past chiming in that it only worked with software rendering, if that's been fixed; then it's not fixed for me either, so perhaps you should submit a ticket. While it's true I may have jumped into this one without a lot of fore thought, I guess I missed the memo on "XBMC 12.1 can do the Crop Black Bars with DXVA" which is kinda new to me, for I've never had success with hardware rendering and 'Crop Black Bars'.
This message doesn't preclude anyone else from putting forth a solution or an idea, so the statement 'the first reply I get seems to be from someone that only read the title and googled it" seems to suggest that only one individual at a time can answer, or that my message somehow diminished your point of view. This is a forum in which we all try to help each other and take a bit of the effort of those who give us XBMC and all the rest, so you can do your bit by posting a ticket.

Just to update this, fiddling around with manual Zoom I noticed my error comes from some sortta calculation error. Basicly some zoom amounts will render me the weird line on right/bottom, some don't.
Writing down some values seems that anything up to -1.33 is alright, then I start getting the line with: -1.34, -1.35, -1.37, -1.38, -1.39, -1.40, -1.42, -1.43, -1.44....
Patk, since u don't get auocrop to work, does manual Zooming works with Dxva there?

Manual Zooming works.... Using the movie 8½ (1963) which has an odd format with a little black on all sides, I was able to use crop black borders while using DXVA although the image expansion was rough... Using software render, the expansion was quite smooth (this might be related to the gfx card drivers).

I am almost definitely sure the rendering problem with some zoom ratios is a driver error. HD 6570 here and if I have all post processing options in CCC disabled then the problem is gone. If I enable edge enhancement, the artifacts are back. I think the driver does not handle some width/height combinations gracefully.
