May be relevant to anyone with this or a similar situation.

Premiere Pro CS6 recognized only the first mono track, and the audio channels menu had the same.

I used ffmpeg to extract the audio from the file (the cameras DO record everything properly, it IS a Premiere problem).

Put this in a *.bat file:
ffmpeg -i “YOUR FILE NAME” -vn -map 0:a:1 -sn audio_ch2.wav

0:a:0 would be track 1, 0:a:1 is track 2 and so on..

Obviously you should get ffmpeg.exe either in the same folder, or modify the string appropriately to point to it.

I am posting this here, because it is the first google find on the topic. I have painstakingly searched the topic, with very little information. Hope it will help someone in here or from google.

I have succesfully updated my EX1 from 1.11 to 1.30
It has fixed a very important problem (for me at least) – SD card support. Before most SDHC cards would produce a ‘Media error’ after a few minutes recording. Now I can put just about anything that passes for an SD card (given it can actually sustain a 5MB/s write) and it records it without errors (test based on 10h recorded on a few cards).

The firmware I used can be found here in a file named item-1.zip:

A simple registration is required to download it.

The update was straightforward enough, took care of everything (including EX1 drivers), overall took about 10 minutes, though I do recommend reading the included instructions as many times as you can before your eyes bleed and continue only if you understand what you are actually doing.

Done on Windows 7, 64-bit.
