Hello!!! I have a combo CDRW/DVD Samsung SM-308B drive (firmware BB02) which was working OK under win95 for some time. Then suddenly, without any obvious reason, DVD playback started to malfunction. The symptoms are as follows: During playback (I am using PowerDVD software) squares and rectangles of different colors appear randomly (not always at the same positions at the same point in the movie), often in sort of clusters so that the picture is distorted, the picture sometimes 'jumps' and usually after a short time PowerDVD crashes (program closes). Playing DVD disc in reverse mode (backwards) seems to be alright. When I rip a chapter to my harddisc and play the .vob file, the picture is still distorted, but the errors appear always at the same places. I tried playing downloaded .vob file in PowerDVD, which played OK. I suspect there's something wrong with my DVD drive, but don't know what it might be, because I do not use it too often and a few days ago it was OK. Can anybody help me, please, it drives me crazy !
