We just discovered a problem using the "create trimmed copies of source media" feature with 24p/24pA DV media; it picks the wrong range of media to copy. Do not use this feature with 24p media until we fix it in the 4.0c update, which is due out shortly. The non-trimming "copy source media" option works fine. We reget the error and apologize for any inconvenience.
