Re: Need a little assistance with transcoding a file - audio issue

Thanks, that strategy did work.  I just wish it wasn't necessary to do 
those extra steps.  In theory transcode should be able to do it all 
without the external extraction and resampling.  I wonder if anybody 
else here knows if there's a proper way to get this accomplished with 
just using 2 calls to transcode - one for -R 1, and one for -R 2.
