Confusing settings for MPEG file

I am getting some confusing information from a client for whom I create lobby display animations. I am creating 30-sec clips at 1280*720, but they are requesting the following specs which seem to be somewhat conflicting:

Format: MPEG-Transport Stream
Overall bit rate: 5 Mbps
ID: 224 (0xE0)
Format: MPEG Video
Format version: Version 1
Maximum bit rate: 5 Mbps
Width: 1280 pixels
Height: 720 pixels
Display aspect ratio: 1.222

They initially requested MPEG-1 files, but I cannot rectify how to output an MPEG-1 Transport Stream; MPEG-2 no problem. And when I try to configure a 1280*720 MPEG-1, I cannot set my bit rate as low as 5Mbps. I am at a loss as to how to set this up in either AE, Compressor or Adobe Media Encoder. Any help? I'll gladly supply further details as necessary to get a handle on this.

Thanks for the reply Walter and for confirming that these are very odd settings. I've been trying to go visit these guys in person to see there set-up, but haven't been able to yet; it's something of an awkward situation (partner and/or competitior kind of thing) My understanding is that they are building their animations in AE as well; do you know if it's possible to "export" out a render module/profile so that I can simply load it into AE for rendering?
