480i video squished

I have 5 pieces of 720x480 16:9 MPEG-2 video that I've added to a Blu-ray. But, when played on my Samsung BD player, it believes that the videos are 4:3.

Here is the mediainfo on one of the videos:
Code:

Time code of first frame                 : 01:00:00:00
Time code source                         : Group of pictures header
Default                                  : Yes
Forced                                   : No
I burn the BD structure from the one created in the IMPORTS directory. A backup is not done.

What needs to be done for the BD player to get the correct playback flag?

UPDATE: Found it... sort-of.

I looked at the M2TS files with mediainfo and discovered that the AR was set to 3:2 and the frame rate to 59.94. That was a result of BDRB doing a VFR to CFR conversion. Why, I do not know. So, I disabled VFR->CFR and ended up with the correct AR, i.e., 16.9. But the frame rate was changed to 19.181. WTF? When that was played, the audio was correct, but the video was obviously slower.

Why can't BDRB just place the video into a M2TS container without screwing with it? Is there a flag for that? There is nothing wrong with the video files, as they came off a DVD. I used DVDFab to rip the files into a MKV wrapper.
