Im pretty desperate, as i just used a lot of money to get VMR9 working properly and now i have this weird problem. Any help is appreciated, even if its just some comforting words :) I have tried illustrating the problem below: 'real' image: ------****------ ------****------ ------****------ ------****------ ------****------ ------****------ etc. interlacing artifact: ------****------ ----****-------- ------****------ ----****-------- ------****------ ----****-------- etc. What im seeing: ------****------ ------****------ ------****------ ----****------ ----****------ ----****------ ------****------ ------****------ ------****------ EDIT: I managed to re-create the problem in Zoom player when using the VMR9 renderer, and playing back an MPEG-2 file captured from another TV program. To my surprise, when i pause the playback the artifact is clearly visible. I took a screenshot [url]http://www.itu.dk/people/petert/_/banding.PNG[/url].
