I bought a new camera (a Lumix DMC-TS5), which takes an SD card for storage. The manual says that it needs an SD Card with a rating of "4 or better" (to take videos), and that cards between 4-32 GB need to be SDHC. I have a couple of old SD cards that are 16 GB, rated 8, but are titled "VideoHD" rather than SDHC. Two questions:
1. Is a "VideoHD" the same as SDHC?
2. The newer SD Cards are rated 10. What's the difference between a rating of 8 and 10?
