I have a Lumix G6 and I have filmed with it several times, but this time I go to record and it just plain doesn't start recording. The camera is on, it is on video mode, a lens is attached, an SD card is in, the battery is charged...there is nothing I can think of that should cause this to be happening. It just won't record. I press the button and nothing happens.
This camera is brand-new. I'm going to assume it's not a hardware problem and that I'm just missing something. Probably something really obvious that I'll feel stupid about later.
Apparently, something must have been wrong with the SD card I had in the camera. I swapped it out for a different one and it works fine now. I wish the camera had been able to tell me, "dude, your card's messed up," rather than letting me continue to be confused.
But, good. At least it's not something wrong with the camera. :)
