DVD Maestro - MPEG2 & MPEG1 mixed DVD

After having tried MyDVD 3.5.1 , DVD WorkShop 1.0 and DVDit PE 2.5, I'm now trying DVD Maestro 2.9.

I love the program so far and I've burned my first DVD consisting of one 720x480 16:9 MPEG2 movie, and a few 352x240 4:3 MPEG1 movies.

All movies play, and the motion menus and buttons all work, however, the 352x240 movies look absolutely horrible when played on my PS2.
It looks very bright and extremely blocky.
The block are so bad that the movies are essentially unwatchable.

However when I play the same DVD from the PC, it looks fine.
There are no blocks to be seen and the brightness level is normal.

Maybe the brightness level has something to do with the luminance setting.
I believe had the "Output YUV data as Basic YCbCr not CCIR601" in TMPGENC unchecked when encoding the MPEG1 movies, although some of them I didn't encode myself so I don't know what was used for them.
For the MPEG2 movie I used 16-235 in CCE.
The MPEG2 movie looked fine on my TV.

I'm still a bit confused by the luminance setting, is 16-235 always right when intending to watch it on a TV, regardless of source?
Or if the source was already 16-235, do you then screw it up by selecting 16-235 again during transcoding?

Anyway, I don't believe that the luminance could cause the blockiness though. (Although at first I believed that the brightness just made them more apparent, but after turning the brightness down on my TV, they were still as bad).

When I did play the MPEG1 movie back on my PC, I noticed that PowerDVD claimed that the file was MPEG2.
When I looked in TMPGEnc's demux, it believed the video stream in the VOB to be MPEG1 352x240.
I then checked the IFO with IFOEdit, and there it listed the video as MPEG2 720x480.

This got me wondering, so I grabbed a mixed MPEG2 / MPEG1 disk that I had made a while ago with MyDVD, that did play just fine on my PS2.
IFOEdit showed the MPEG1 video of that one as 352x480 (MPEG1 CVD?) while the movie itself is 352x240.

So I'm suspecting that my PS2 gets all confused when it gets the wrong info about the movie in the IFO and resizes or does something else weird to cause blocking.

Now my real question is:
-Did I set something wrong in DVD Maestro that caused the movie to be listed as 720x480 MPEG2 when it is in fact a 352x240 MPEG 1 movie? (The menu that was calling the movie was 720x480 for example, maybe I shouldn't use that res for the menu).
-Or is this just something that DVD Maestro does to MPEG 1 movies?

Anyone, anyone ..... Bueller?

I tried changing the IFO files created by DVD Maestro to MPEG1 but that had no effect.
There must be something different about the way that DVD Maestro handles MPEG1 files versus what MyDVD does.

Maybe pictures will help.
