Has anyone tried to use 8cm DVD's in their DVD player. More in particular the DV88. I've just bought a DVD camcorder from Sony and tried to play a finalised DVD but it kept on making slight scraping noises as if it couldn't 'pick up' the disc before displaying No Disc on the screen? I'm thinking it's because my player is probably nealry 5 years old now and may be having a bit of trouble recognising the format. Any ideas/suggestions?
