I've been looking at your log in this post. It looks like the reason your bitrate is dropping on "Rocky" is because you'd set a target size that is greater than 8500. When BD-RB sees that, it assumes you are writing to something larger than a DVD-R. So, it removes the restrictions. One of the restrictions is that large audio streams are reencoded to AC3. You'll notice that in the first log you see this:
Code:
 - [22:18:17] Processing audio tracks
   - Track 4352 (eng): Reencoding audio to AC3...
for your first encode, while you see this:
Code:
 - [19:50:51] Processing audio tracks
   - Track 4352 (eng): Keeping original audio
in your second log. The bitrate is dropping because you have your audio settings set to not reencode to AC3. When outputting to DVD-R, the audio is always reencoded because of output disc size. Setting the target above 8500 tells BD-RB you aren't using DVD-R.


In your second example (outputting to DVD-5) you are undersizing because BD-RB reached the maximum bitrate that can be used on a DVD-R:
Code:
 - [09:04:34] Reencoding video [VID_01227]
   - Source Video: MPEG-4 (AVC), 1920x1080
   - Rate/Length: 23.976fps, 2,052 frames
   - Bitrate: 15,000 Kbs
There's nothing BD-RB can do about that, because increasing the bitrate would very likely make the disc unplayable by violating the DVD-R's maximum bitrate standard.
