Anyone had issues with "Movie recording stopped automatically" happening after about 10-15 seconds after recording? I can't get shots longer than 15 seconds in raw mode. I set it to "skip frames" when buffer full, but buffer usage never goes above two stars (**). I tested on KomputerBay 128GB and Lexar 1000x 128GB, they both get about the same write speed, 82.9-83mb/s. I'm shooting 1920x1080: I notice 82.9mb/s is the minimum required for that resolution, so I guess the recording stops because my card keeps dipping just below that minimum speed? Maybe I need to try the SanDisk 128GB?
