cropping dvd movie

[comicfanman]

Ok I just bought some very old movies from someone. They transferred them to dvds themselves. When they did this they put
some kind of logo in the bottom corner of the movies all the way through. I don't have to remove it or blur it out. I would be happy just with cropping it out.
Is there any software that I can use to do this without converting the dvds format? Any and all help is appreciated.
Thank you

Nope.

You cannot crop, blur, resize or do anything that effects the actual video image without re-encoding the video. You also don't want to crop the video, as this would make it non-compliant for DVD. You would have to mask the area instead, or if you did crop it, replace the cropped area with black bars.

All of this is doable, but it means ripping the DVD, extracting the video, using a tool like virtualdub or an avisynth script to crop the section you don't want, then replacing it with black, re-encoding the video back to DVD compliant mpeg-2, then either re-authoring the video into a new DVD, or inserting the new video into the old DVD structure.

Is the logo annoying enough to justify this effort ?

A strategically placed bit of masking tape comes to mind, if you don't want to take the quality hit from re-encoding. Or if you're playing it on a PC VLC among other players can crop it during playback.
