I have to output an mpeg2 file for a media player. The specs say it accepts 720p and MPEG2 or MPEG1 only. When I try to output an mpeg2 at anything other than 720x480 it does not work. Does AE not have this capability? Is it possible with an MPG 2 at all? Please Help

Mpeg2 is does not support frame sizes other than standard-def. If you are using After Effects CS3 or higher with the production premium bundle (encore, premiere, etc.) then you will have Mpeg2 blu-ray output settings available in After Effects output module, which supports HD output settings. That is the setting you need to use for 720p output.
First, be sure your comp is set to 720p:
When you add your comp to the render queue select the Mpeg2 Blu-Ray output module preset:
Now open your output module settings and the format should be set to MPEG2 Blu-ray. Click on the "Format Options..." button to open up the blu-ray output settings:
Now set the Frame Dimensions to the 1280x720 preset and your done (except for rendering, of course):
I would leave all of the other blu-ray settings alone, including the quality slider because the default settings will give you the most compatible file possible and the quality is very good. I use the 1080p blu-ray setting all the time for our Leitch video server for broadcast and it works flawlessly.
