480i h.264 being recoded

I have an old video clip that is 720 x 480i which I wish to occasionally serve back to the TiVo. When I code the video as h.264, however, pyTivo believes it needs to recode back to MPEG-II before pushing back to the TiVo. I don't have this problem with any 1080i or 1080p files. Is there any way I can get pyTivo to push this without recoding it?

Code:

You probably have to recode audio to AC3 or AAC to get it to push natively.

Pfft! Oh, of course. I wasn't even looking at the audio.
