[QUOTE="Larzon, post: 648902, member: 101335"] Yup - tons of dropped frames there. This points to a "weak link" in the chain. I suspect your ATI 4200 GPU is trying to perform deinterlacing but cannot keep up. See useful GPU performance info here (thank user moviebug for link): [url=http://www.missingremote.com/index.php?option=com_content&task=view&id=2564&Itemid=232&limit=1&limitstart=1]Missing Remote[/url] Things to try: 1.
