Just FYI, I bought a 64 GB SanDisk card -- SanDisk Extreme SDXC -- for the DVR-207, despite the fact that it says it only supports a SDHC card up to 32 GB. I've been using the 64 GB card for a few days with no problems...worked as soon as I popped it in. The card was almost as much as the camera, but I didn't want to have to worry about space. At this rate, I'll probably go 2 weeks before it starts to overwrite the oldest clip. Just FYI.
