Doom9's Forum - View Single Post - How do I crop the 8 blurred lines caused by Radeon cards during DXVA playback?

I have tried with various versions of MPC-HC, and am using the built-in DXVA decoders. I believe the problem was also there when using PowerDVD's decoder. Plus, this issue also seems to show up using my FusionHDTV card's software to playback live TV (1080i stations only show this problem, 720p stations are fine) so I don't think it is a problem with MPC-HC, but rather ATI's drivers or implementation of DXVA playback. When playing back a full Blu Ray disc in PowerDVD though, the problem is not there, so I guess PowerDVD is able to crop the 8 lines itself.

I find it surprising that not many others have noticed this issue, but then again most Blu Ray movies are in letterboxed format, and when the 8 repeated lines are black, nothing looks blurred.
