Digital Camcorder Memory Card/Battery Questions?

Question

I just bought a digital camcorder, its a DXG-505V. I've got an upcoming family reunion and I'm wondering how much much recording time by batteries and memory card should allow me. I've put a 2 GB SD memory card in. The camera records in AVI if that makes a difference and the image size is 640x480. It runs on 4 AA batteries. The big question is which will last longer the batteries or the memory space and about how long is this going to be? Thanks.

Answer 1

1 hour of AVI is records about 15 GB
