DVD Bitrate Viewer (includes audio plus video plus subs plus overhead). And DVDs don't contain AC-3 PCM. AC3 (probably what you want) or WAV or (if PAL) MP2.
Most retail DVDs use variable bitrate with the max bitrate around 8000. Some lower, some a little bit higher. I daresay you will never find a retail DVD with a max video bitrate of 9800.

What kind of "retail tapes?"
How do you know "these files" were the same source for the retail DVD's ? How do you know they didn't use something else or undergo some other path ?
Movies / TV series such as dramas are progressive content. In North America this means you should be performing inverse telecine to recover the original progressive frames. Then you should encode progressive and make a progressive scan DVD. Progressive content, but encoded interlaced or with telecine is significantly worse - You encode 25% extra fields. So at a given bitrate, the quality will be worse.
Soap operas, or documentaries, sports shows - those are usually interlaced content. Those you would encode interlaced
The problem with 9500-9800kbps is potential playback problems in some DVD players, such as older models, and cheap imports
A good free MPEG2 encoder is HCEnc . A GUI for it is AVStoDVD . There are commercial encoders such CCE, Mainconcept, Procoder . Each has pros/cons, but FFmpeg is clearly the worst - By far.
And if you're worried about bitrates, quality, why use DVD-video at all ? Many TV's these days can play files natively, such as h264 / MP4/MKV. Or a cheap android box can be used as a media player
Bitrate viewer and loaded a few DVDs. Here is one of the statistical results that came back.
[Attachment 53621 - Click to enlarge] I've learned something new today thanks to you. I appreciate the guide from you. So It turns to be the max bitrate is 9879 kb/s and the average bitrate is 4491. But the quality is awesome!!!! I just don't know of any methods or Softwares that are capable of converting uncompressed MOV files into DVDs with the correct bitrate, resolution pre-determined. Could you please throw at me some good tips? I'd appreciate your help.
This is my command line to convert the uncompressed 10-bit 422yuv files to MP4 without cropping.
for %%a in ("*.mov") do FFmpeg -i "%%a" -c:v libx264 -preset slow -crf 0 -c:a aac -b:a 192k "\%%~na.mp4"
for %%a in ("*.mov") do ffmpeg -i "%%a" -pix_fmt yuv422p10le -vf crop=720:480:0:3 -c:v libx264 -preset slow -crf 0 -c:a aac -b:a 192k "\%%~na.mp4
-vf crop=720:480:0:3 means you're cropping 3 from the top , 3 from the bottom - is that what you wanted ?
You need to look at the actual image and correlate. ie. What area are you cropping ? When you cap at 720x486 usually there are some garbage pixels on the borders. Make sure the crop corresponds to the correct area
that "3" means the y position of the crop box. x=0, y=3
Also, most retail DVD's from an analog source will mask out or crop and add borders to the garbage areas if there are any . They look bad and impair compression

That DVD sample is actually interlaced content, shot on video
Could you please throw at me some good tips?
AVS2DVD. Sadly, it fails to convert uncompressed 10-bit MOV files to DVD. It froze for like forever, and then crashed. I guess my uncompressed files are way too big for it? 100Gbs and up.
If it's "freezing", it might be indexing the source. The speed depends on your hardware, drive speed etc..
You can actually use LSmashVideoSource("video.mov") and it won't index the source
I'm just guessing that's the reason why it's freezing. If you wait a few minutes and it unfreezes, that could be the reason why
If that's the reason, you can create an avs script, and feed that into avs2dvd (it accepts avs scripts).
But it seems to freeze for me too with 10bit input, not sure why. I actually don't use it. It freezes with a script converting to 8bit script too, that works in other programs - not sure why. But it works ok with 8bit directly
But I sometimes use hcenc directly, and other tools to author. This works ok with a valid script. Hcenc is only the encoder, you still have to author the DVD, make menus, etc...avs2dvd does simple menus, authoring if you can get it to work
This converts to 8bit 4:2:0, downsamples interlaced
LSmashVideoSource(v210.mov") ConvertToYUV420(interlaced=true) ConvertBits(8)
