16:9 DVD video - how to get the original format without reencoding?

[Weef]

Hi, I'm just having here a 16:9 NTSC DVD video source.
My goal is to restore the orginal video format.
Is there a way to change the PAR or SAR values without re-encoding the whole video?

If you just want to adjust AR (e.g. if it wasn't set properly in the first place), you can try restream or dvd patcher. But any restoration efforts will require re-encoding

Ahhh, restream seems to be good enough for this purpose.
Would be quite desirable to have a programm that could demultiplex and change it to 1:1 in one step^^

DVD video is never "1:1". None of the available pixel aspect ratios give square pixels.

Cheers,

Ok so then wht do I do when I change it to square pixels...I know the DVD doesn't have that setting...but what you are saying is just a little confusing to me o.o

You resize and reencode. DVDs are only 4:3 or 16:9, never 1:1.

Well, it seems to have worked with restream
