When loading a DV tape from a Sony video camera into my PC computer (XP) using Adobe Premiere Elements version 3 or 4 using a firewire connection, only one of the two stereo channels is recorded. The screen shows two channels being recorded but they are identical. An earphone verifies that the video coming from the camera has two separate audio channels. Is there some setting that I need to set in Premier to indicate sterio input rather then mono input? Does Adobe Premiere Elements only process mono inputs? I've tried two different firewire cables, two different Sony cameras, and two different PC computers, all with the same results. Advice please.
