The JVC GY-HM710U takes SDHC Class-6 (or higher) cards.

Could I use an SDXC card on a camera that takes SDHC?

I'd like to think that SDXC cards can hold more, so I'd like to buy those over the SDHC cards and use those for the JVC GY-HM710U.

Will the SDXC cards work with this JVC?

(and if I buy a 64gb class-6 card, I assume the camera will not have issues with it?)

It doesn't say in the specs that it can accept SDXC cards. However, even though technically SDXC cards are designed for more data, are there any cards that are being sold at higher rates than SDHC?

AFAIK, the professional grade cards from Sandisk top at 128 GB.

Here's some info from Wikipedia:

Compatibility with SDHC

SDXC host devices accept all previous families of SD memory cards.[26] Conversely, SDHC host devices will accept SDXC cards that follow Version 3.0, since the interface is identical,[3] but the following issues may affect usability:

SDXC cards are pre-formatted with Microsoft's proprietary and patented exFAT file system, which the host device might not support. Since Microsoft does not publish the specifications of exFAT and its use requires a non-free license, many alternative or older operating systems do not support exFAT for technical or legal reasons.

SDHC host devices will not test the new capability bits defined for SDXC 4.0 cards. It will therefore not be able to use the new features of SDXC, such as transfer speeds above UHS104 (104 MB/s).
