IS that possible?

Hello Everybody! I'm new here with a strange question.

I have digged up the similar forums to get a solution to my problem without success.
So I required to make a footage with the following settings:

Mpeg2 TS
Video: 720x576 h264 AVC 1.8Mbit/s
Audio: Mpeg1 Layer2 256kbit/s

It seems impossible for me now, beacause all the encoding templates are different from this one. H264 automatically comes with mpeg4 aac audio codec, mpeg1 layer2 audio codec automatically comes with Mpeg2's mpga video codec.. so i'm clueless in it.

How do I make this format? Thanks for your help!
