Ive been recently recording some Japanese (NTSC) videos from my VHS player, through a Digital video stabilizer and into a standalone DVD recorder. Im in Australia, so my recorder will be PAL, but it supports NTSC, as i can watch and record NTSC signals/DVDs.
Anwyays, When i record the VHS video onto the DVD recorders HDD or onto DVD. It plays fine on the original standalone DVD player, BUT when i play it on the computer, or rip it into VOB using DVD decrypter, there is severe deinterlacing going on. its really jaggy with all those missing horizontal lines showing, especially during high motion scenes.
Why is this? its fine when watching the original NTSC VHS tape, and even when i watch the recorded footage on the DVD recorder. But on the PC, its all deinterlaced and bad.
Is there a way to fix this, is it the VHS player's fault? or the DVD recorders? i make sure the setting on my DVD recorder (pioneer DVR-530H) is set to NTSC mode.
any help would be awesome, thanks

I think your interpretation is backwards. The DVD recorder or TV is deinterlacing so you see no comb artifacts, whereas the computer isn't so you see comb artifacts. Try using a player that deinterlaces on the fly.
Post a short sample where the problems are obvious.
ok here we go guys !
so when i watch the original VHS, its normal, no issues, but when i record the VHS into DVD using my standalone DVD recorder, the resulting captured DVD plays fine on the standalone recorder, no visible issues, BUT this is it on my PC. The deinterlacing is bad mainly in areas of high movement, (because they are music videos, its frequent).
here are some screenshots.
edit: ok so this ^ is without any interlacing filters on in VLC media player, if i play it in a higher end player like WINDVD then the deinterlacing isnt noticable much, but what i want is the original DVD / VHS footage im playing to be recorded by the DVD recorder without any of this deinterlacing happening. im not so worried about the playback, moreso i just want the best quality recording of the tapes without this deinterlacing happening. Anyone know how to fix it? I dont know whether its the settings of the DVD recorder, or if its the VHS player, or whether its what happens when you record NTSC with PAL player, using PAL60. (my player supports NTSC though i think). Maybe this wouldnt happen if i used a NTSC DVD recorder?
I was hoping you would post a short video sample, But, yes, it appears the problem you are having is that the computer is not deinterlacing. So you see both fields at the same time, rather than one field at a time. Use a player that deinterlaces on the fly, like VLC. Enable its deinterlacing with Video -> Deinterlace -> Bob, or any of the other deinterlacing algorithms.

The DVD recorder is doing exactly what it should do. It is not a fault. Deinterlacing the footage to put it on DVD would lower the quality and throw half the spatial resolution away.
You just need to use appropriate playback software on your PC.
Most PC DVD playback software deinterlaces automatically by default. No idea why yours doesn't.
