When using the smart streching mode the screen is broken into vertical sections that are not adaquate aligned. It looks like there is a vertical line of pixels missing between the sections. I have included two screenshots out ouf the forum.

What I found out so far:

- Only MPEG2 videos are affected. All other formats are fine.
- Problem occurs with ffdshow, powerDVD and MPC video codec.
- I assume it is only related to nvidia cards and VMR9. No such issue with EVR.
- I tried disabling DXVA and nonsquare mixing without succes.

I really like this smart streching mode, as you do not have to change AR on the TV and I cannot believe that I am the only having this problems. Any help is welcome. ;)
