I don't disagree with you at all. I mentioned these weren't meant to  
be formal submissions in my first e-mail:

These were submitted as a record of what I've done, and the profile  
information from my first e-mail explains what is required to create  
iPod-compatible H.264 videos above Baseline Level 1.3. I never  
expected them to make it into the source tree as-is.
