Jeff thanks for the input..I have spoken to the support guy for the hardware that does the final encode for air. ..unfortunately the specs he sent me were a screenshot of the Adobe Media Encoder for Mpeg2, which I had already been using, to no avail. Its one of those situations where they came in and did the install ..trained the folks here how to run it, and then provide support by email/phone. It may be something as simple as a marginal encode computer or local setting, but I have no way of knowing, or getting anyone locally to take the time to investigate it. Just was hoping someone here might have run into similar circumstances.
