If you try Audacity (which is freeware) you'll see what I mean about being able to split/combine channels - it's an extremely handy function. Audacity looks like Nero Soundtrax but has many of the editing features of Nero Wave editor - except it's not as user friendly.
Anyway, thank you both for the info.
trevtdogg, if I were to use Nero to save one channel, I would do this: TOOLS->Stereo Processor. When that Tool opens, click on "Presets" and pick either "Only Left" or "Only Right," click OK, then save the channel as a Mono wave.
Is this your method, or would you do something else?
