Bitrate calculation issues

I had some oversize problems with the latest Alpha, here are the details:

Source is an XviD file, duration 1 hour 57 minutes.
Destination DVD-5, Audio 224 kbps AC3.

My reference is good old DVD2SVCD, it calculated a video bitrate of 4955 kbps, and the resulting file did fit perfectly on a DVD-5 (ImgBurn reported 99% fill rate).

With AVStoDVD the video bitrate varied depending on the output format:

For DVD structure, ISO image or Burn DVD the bitrate was 4927 kbps. This did work perfectly.

But when selecting Elementary Streams or Muxed MPEG2 files the video bitrate was 5037 kbps, and these files could not be burned to a DVD-5 blank, they were way too big.


What is wrong here? I think the video bitrate should be the same no matter which output format is selected.
