I have lots of DVDs like this. I need to enhance the quality while upscaling. Please take a look on this.
Post your 720 encode and avisynth filters/script used for that!
Looks to me like the source for the DVD mastering was videotaped with a NTSC camera from a cinema screen or something like that, because of the black pulses every second or so.

So because of that, you should encode at 29.97fps and this is the best you will get out of this source I think:

Code:
DGDecode_mpeg2source("C:\VTS_02_1.d2v", info=3)
qtgmc(preset="very slow")
selecteven()
crop(2, 80, -4, -80)
spline64resize(1280, 480) #resize for correct 2.66:1 aspect ratio
Yes it looks like the source is a 2.66:1 aspect ratio. It is VERY unusual, but after looking closer into it, I am 95% sure it is a 2.66:1 native aspect ratio image.

This is the best you will be able to get out of this source. No need to have a higher resolution, as the source is really bad.

EDIT: I've now checked if it could be a 2.76:1 resolution and by the looks of it - it's very likely that its a native 2.76:1 resolution, which would mean you would need to resize it to 1280x464. Yeah when you look at frame 1277 after deinterlacing, it seems to me that the correct aspect ratio is 2.76:1.

So you will need to use spline64resize(1280, 464).

Its really even more unusual for the aspect ratio in movies to be 2.76:1, but it seems to be the case here, Im quite sure.

SO this is the script youd need:

Code:
DGDecode_mpeg2source("C:\VTS_02_1.d2v", info=3)
qtgmc(preset="very slow")
selecteven()
crop(2, 80, -4, -80)
spline64resize(1280, 464) #resize for correct 2.76:1 aspect ratio
Yes my friend, the correct aspect ratio is sometimes a little tricky to figure out, but is very important imo
