Hi all, I've got a new GS6000 A7 with the latest standard f/w on. I've got an issue with it where it's marking recorded files as "Invalid". It's got a class 10 Sandisk 32GB card in it. I've reformatted the card in both a PC and the DVR itself without error and tried it again today with the same result. I'm about to send it back to Amazon for a replacement but wondered if anyone else seen this?
