I have a year and a half old sony camcorder DCR-HC30. Working great until on day I turned it on and it said 'use infolithium battery pack'. Of course I had the battery on it already. So I bought a new one, charged it all nite. Tried it again in the am, same message. Anyone else had this problem, or know what is going on with it? It works fine if it is hooked into wall power...thanks
