Audio tracks on IMovie HD

[lombard1951]

I have some DV footage of a presentation which has audio recorded on only one channel (L). As this is speech, I would like it to appear on BOTH audio channels when I get to edit it. Although I can extract the audio in IMovie HD, there doesn't seem to be any way to duplicate the audio onto L & R channels, even as mono. Any solution to this?

Also, when exporting the finished IMovie to .rm format, there is a noticeable time lag, as the audio is about .5 to 1 -sec behind the video! Ouch! I have tried different settings under "Expert", but to no avail. I am exporting at these settings:
512 DSL/Cable
Audio: Voice
Video: Normal
Video quality: Standrad 1-pass (2-pass and it is MUTE!)
Dimensions: 320x240

Any suggestions as to how I can fix this?

For your first sound problem, you might have to use garageband to copy the sound into the right track. In FCP, I know that you could copy the sound into both sides, but I don't know if thats possible with iMovie.

About your second question: what kind of computer do you have? I had similar problems with my 450 mhz powermac agp, but it's now been upgraded to 1ghz and works fine.
