artifacts in "Ren and Stimpy" caused by NTSC DVD in PAL player ?

[HenkZ]

I bought all "Ren and Stimpy" DVDs on NTSC. But when I look at
them I notice something that looks like digitization effects (dark lines
are ragged). I am watching them on my DVD player which is a PAL
player. Could that be the reason for the artifacts ? Would it help to
convert these DVDs to PAL ?

The effects are much less noticeable when there is a lot of motion, but
on 'static' parts it's very visible. It is also possible that the digitization was
done poorly (also because these cartoons are slightly older), and then
converting won't do a thing.

Could I please hear your views on this ?

Converting these to PAL might actually make things worse.

It's impossible to say. It could be that your DVD player is doing a bad job of converting the discs to PAL output. Are these legitimate DVDs or did you save money by buying bootleg copies? It could be how they were encoded. They might be encoded progessive and you are trying to watch them on a standard definition TV - standard definition TVs can display the problems you see when progressive video is shown on them. You might have your DVD player set to progressive output but you don't have a TV capable of accepting progressive input. These are just a few ideas.

You don't say what kind of signal your DVD player is outputting from NTSC discs? It could be true 50Hz PAL in which case the artefacts you mention above would be unlikely or it could be 60Hz "quasi-NTSC" which some european TV sets do not like at all.
