[Solved] blotchy films

[ron101]

My video 1080p is playing all blotchy, (little squares all over the screen.) 720p, 480p etc and below it is perfect. I thought it might be the MCH-HC X64, but it does it on VLC to. I have had trouble with the Jdownloader but after i had put the CFG from the old to the new it has slowed up on the LINK GRABBER page and the DOWNLOADS page, so much so that it takes 5min - 10 mins to capture anything even 1 file. So it does it on MHC & VLC, I haven't tried any more. So i think it must be JDownloader, are you free to advise??
