Issues dumping laser disc games

Hi there.

I'm trying to dump my LD games but I have some problems using it with openMSX. It appears sound scratches, or the image freezes and some more issues.

I follow the next steps:

- Capturing the video with a video capture (Elgato Game Capture HD) in .mp4 (at highest params).
- Captured using the Elgato app or OBS.
- Converting to .ogv container with ffmpeg.exe manually or VLC.

The results viewing with a video player is very good, the sound and the image are perfectly clear, but when I try to use in openMSX, allways appears some issues.

Is there a way to dump easely?, how are dumped the games that are preserved, any guide to do it?.

Thanks and regards.
