Does quoating the above mean that the following applies

After you click the "Save As..." button, the "Save As"/output
window pops up. In the bottom right corner there is an "Options"
button. One of the options is "Bit Rate:", set it to 8Mbps. But
this only changes what is recorded in the header, it has no actual
effect on the video. It may make the clip acceptable to other
programs though.

Did you tell TDA to ignore the warning about two of your
three clips? If not that may be why they aren't there. How
many VTS are there, in the VIDEO_TS folder? VTS_01 ,
VTS_02, and VTS_03 or just VTS_01?

There is certainly something wrong with the clips. We
need to establish what their parameters are. If they are
the MF4 files you passed through a two pass encoding
then you should have those parameters. ( As you said
that your source was a DVD, you should not have needed
to do that encoding, by the way. And it could be the cause
of the clips, that came from a DVD, now not being DVD
compliant. )
If the clips are not some of the MF4 clips, then were they
extracted from your original DVD? If so, how was it done?
Did you try the TDA "Add DVD video..." button process?
Did you copy the .vob to your hard drive and use VideoReDo
on them?
Luck;
