Irritating lines in DVD files

I’ve got a few dvd files (VTS / VIDEO_TS) on my HDD that I want to rip to DVD but they have got these irritating lines on playback.

The edges of all the video parts have lines and all the movement is unclear, its just lines. I’ve watched these files on 2 PCs and it does it on both.

If I encode and burn to disk using nero the lines appear on the dvd aswell.

Is a codec issue? Pls help
