I'm trying to capture some still frames from video I have shot. In the memory stick menu, under Still Set, Image Size, there are 2 settings: 1152x864 and 640x480. I have selected 1152x864 but the captured jpegs are all 640x480. I know this worked fine a few years ago. Does anyone know what could be causing this problem? It's very frustrating since this is a huge difference in resolution.
