Hi all, This problems p***ing me off big time. When im watching certain tmd avi's im getting a good picture.However when im converting to mpeg in TMPEG im getting weird purple macro blocks filling the screen every now and then.I have the latest Nimo codecs installed as a standard installation, and im encoding in highest quality.Ive tried different drivers for my geforce 3 but this has not helped the encoding problem.Ive tried to re-encode to a divx 5.02 but this dont get rid of them damn purple patches either.If anyone has got a solution to this i would be very grateful?
