I tried that myself, nohandluke. The only solution I came up with was recording the sound effects during playback using Perfect Sound Recorder, then cleaning up the resulting mp3 files.

I also managed to record snippets of landspeeder effects from the Original Radio Drama. By cutting out dialogue, and with some tinkering, I managed to get a decent, steady landspeeder "hum" effect, which I sent Adywan. Not sure how good the quality was for what he needed it for, but it's about the best I could do -- landspeeder effects don't seem to be plentiful or readily available.
