I'm not sure what that first number is for, but I don't think it's average bit rate. Here's what I get for gd1980-10-31d1:
Stream: VTS_01_1.VOB
Type: VOB program stream

Duration: 0:49:57
Data Size: 3.75 GB
Bit Rate: 10.76Mbps

Video Tracks:
224 MPEG-2, 704 × 480, 4:3, 29.97 fps, 9.80 Mbps , upper field first

Audio Tracks:
160 PCM stereo, 48 kHz, 1.54 Mbps

Stream Files:
VTS_01_1.VOB (1000.00 MB)
VTS_01_2.VOB (1000.00 MB)
VTS_01_3.VOB (1000.00 MB)
VTS_01_4.VOB (845.08 MB)

Here's Mattman's info:
Video Source: Low generation closed circuit pro-shot broadcast
(704 x 480 29.97fps NTSC VBR, average=8528 Kbps , peak=9831 Kbps )

Audio Source Set 1: PreFM>MSR>R>C>DAT>WAV>SHN
Audio Source Sets 2 and 3: MSR>R>C>DAT>WAV>SHN
(LPCM 1536 Kbps Stereo 48Khz)

It gets the audio info correct but only gives the max bitrate. I'm not sure what that other # is because it's not the avg for this disc...
