Tim:

Thank you very much. The second time was the charm. I did a lot of experimental clicking after I couldn't get things to work at first so I'm not totally sure what the problem was. But I suspect it was that I was not doing the selecting properly before pressing the S key. Thanks again for your very prompt and detailed help. You might see me in the forum again pretty soon as I'm running into a few conversion issues involving Vegas, MPEG-4, and .mov files.
