Yes, there are several ways to create smoother results...

First question is if your source is progressive or interlaced. If the source is interlaced then you do not have a choice. AVStoDVD will automatically use the preferred method for the conversion which will result in an interlaced PAL DVD. And this resulting DVD should play just as smoothly as the source.

But if your source is progressive then you do have choices. Pans will be juddery if you use ChangeFPS for the fps conversion. Under "Preferences -> AviSynth" you can specify the method for hard fps conversion. The "Insert/Drop Frames" option does use ChangeFPS. Using "Blend Frames" uses ConvertFPS instead. Looks smoother, but you will get ghosting. "Motion Compensation" uses the MCJMFPS.avsi script which interpolates frames. Should be very smooth, but depending on the source characteristics you may get some artifacts (most often warped vertical lines).

The last option is not included in the A2D options, you need to edit your AVS script manually. This option will not drop whole frames like ChangeFPS, it will drop fields instead which looks much smoother. The downside is that your result will be interlaced. Here is the script:
Quote:
# Insert after the resizer


Last = Video
Interleave(Last, Last)
ChangeFPS(50) # Drops Frames
# ConvertFPS(50) # Blends Frames
AssumeTFF()
SeparateFields()
SelectEvery(4,0,3)
Weave()
Video = Last


# The encoder must be set to "Interlaced".

//EDIT//
Just saw your edited post...
NTSC slowdown won't help you here. This option applies if your source is PAL progressive (25 fps). When this option is ticked, A2D will slowdown 25fps to 23.976 fps and then add soft pulldown flags to make the output fps 29.97 fps.
