Is this the H20 ntsc dvd?
I had a quick look at it, didn't find any problems.
Ripped vobs, ran dgindex.exe. Used this avisynth script:
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\dgdecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\tcomb.dll")
Mpeg2Source("S:\temp\h20\h20.d2v")
Telecide()
Decimate(5)
crop(0,100,0,-102,align=true)
#correct aspect ratio for 1:1 pixel ratio displays (like pc monitors)
#Lanczos4Resize(720, 306)
#OR
#resize to anamorphic
#Lanczos4Resize(720, 360).Addborders(0,60,0,60)
Use the crop and/or resizer (one of them) if you want, hope I calculated correctly :)
Edit - Note:
If you want the highest possible quality ntsc anamorphic dvd you might try obtaining a pal version of the movie - this will have higher vertical resolution (unless they really messed up and upconverted from ntsc...).
