Hiding burned-in subtitles

[junkan]

Hi All,

I have TV series with burned-in subtitles in the wrong language.
I have the srt files with the subtitles in right language, but the overlap between 2 texts doesn't make it easy to read.

I'm looking for a way to hide the "wrong language" subs:
1. Having a rectangle behind the text read from the srt file?
2. Showing the subtitles ina separate window (so that I can move it on top of the area where wrong subs are displayed)?

Any ideas are welcome!

Thanks

If the unwanted subs have a constant position, you can override them with the logo filter (using a completely uniformly black logo image).

Yes, that would be perfect.
Is there a place where I can find how to use this "logo filter" feature?

EDIT: Let me ask this differently
I found the Tip "http://wiki.videolan.org/How_to_add_logo" but I can't figure out how to set the position of the black logo.
I created a black rectangle named logo.png
Question 1: I use a Mac, so the VLC binary is actually VLC.app, and I usually start it from Finder. How do I specify parameters?
Question 2: The parameters I need to use look like: vlc --sub-filter logo --logo-file logo.png video.avi. Where do I specify the x and y position of my rectangle?

Many thanks

Any update?
