Hi All (Again 
),
Thank you very much for this forum and all the posts on. It is really hellpfull to start to better understand how what with actionscript.
Before the arrival of QT7 I was using this script to create some preview of audio files. Basically, I can set a begin point, the duration and automatically extract this portion to a new file as .wav.
QT7 add new great features to quicktime, but also break this script. I cannot handle at this time what exactly is going wrong. I see something like a wrong type on “time scale” but not sure at all…
If someone have an idea on it, that could be fun. Maybe an english lesson too 
sorry for my frenglish.
