hello Alex, if you remember about 2 months I reported that the April release ( i think) had that problem that let the recording stop at random due to high bitrates for some videos with no reason. I used that firmware for a project and still had the problem when you released an upgrade when I thought it was fixed. Now I installed the latest stable version 2.0.1 but at the first recording it happened again, buffer full! The card is not the problem with canon firmware it never happens and with ML I'm using the original FW bitrate.
