This was apparently hiding in the iPodderX support forums, I guess I just didn’t search hard enough. Thanks to Ray and August, themselves, for explaining this to me, in person. The fix is to go into iTunes, open preferences, and on the import tab, use a custom encoding rate. Change the channels setting from Auto to Stereo and that will apparently make the crashes go away. I’ll let you know my results, but they knew exactly what I was complaining about after only a few words, so I am optimistic.
Thanks, August and Ray!
