I have been recording our school play this year and my camera's heads have been dirty but I've been cleaning them regularly. I got my dad to record it with his school's camera (Canon MD225) and I also recorded it with mine (Canon MV920). We both used LP and MiniDV tapes. My camera stuffed up recently with the sound cutting out all the time with just flickers of it every now and then for less than a secod and the picture breaks up really badly in the middle. It imports fine mostly with the MD225 but still get some pixelation and break-ups in the middle. Although not as bad as the MV920 it's still not very good to work with. Any suggestions?
