[QUOTE="peque, post: 852112, member: 54451"] Ok. I understand. Oops... You have reminded me something... nevcariel implemented "aggresive" deinterlacing option in LAV Video decoder in response to a report from myself about another (this time SD) spanish DVB-t channel recording that wasn't correctly deinterlaced. He told me that the problem was that the recording was flagged as interlaced, but from time to time, the video frames weren't flagged, so deinterlacing was "lost" then.
