I just got it and am figuring everything out. It's not too difficult but I've read the manual, and watched online tutorials, and I cannot find how to fix a couple of things. Sometimes the sound will not play, and I don't know what caused it to be silent. I have been having re-open it again just to get sound. It's not my speakers since other things will play. And when it comes to recording sound my field recorder records in stereo only. So I have to delete the empty channel, but have not been able to find how to do it. Every attempt effects both channels. Thanks.
