In the meantime, as new C stuff is hammered out, tech support advises that I slip into something more Soundblaster-compatible. Here's the polite letter, which I'm not complaining about, simply sharing:
Hi Kirby,We found that this is a specific issue with Realtek intergrated sound card. We are currently working on ways to accommodate the rare integrated type of sound cards that seem to have issues with Camtasia.In the meantime I would recommend purchasing a Sound Blaster sound card as we have always had good success with those working with Camtasia.Please let me know if you have any questions.Kind Regards,Mike

On the other hand, those Camtasia movies were more "proof of concept" and're still out there doing work, so I'm not all that knickers-in-a-twist (as Brian might put it) over the vacation I'm getting from making more mathcasts and/or pilots for ~M!. Let's give would be sponsors ample time to evaluate the merchandize. I don't believe in being too pushy.
