Hi!

If by "embedded" you mean permanent subtitles that are part of the .AVI itself:

To eliminate subtitles from (DivX-compressed or other) .AVI videos

If you are fortunate enough to have the subtitles appearing below the movie image (rather than across the image itself, you can "erase" the subtitles by using VirtualDub as follows (it's not as complicated as it sounds):

1) Load the .AVI into VirtualDub (or one of its variants)
2) Set "Audio" to "Direct Stream Copying"
3) Set "Video" to "Full Processing Mode"
4) From under the "Video" dropdown menu, select "Compression" and select the same codec and settings that were used for the original .AVI
5) From under the "Video" dropdown menu, select "Filters"
6) Click on the "Add" radio button
7) Doubleclick on the "Null transform" filter
8) Click on the "Cropping" radio button
9) Enter the proper amount in the "Y2 offset" (at lower left) to cut off the subtitles
10) Click on "OK"
11) Click on the "Add" radio button
12) Doubleclick on the "Resize" filter
13) Under "New width and height" enter the NEW dimensions of your cropped video (e.g. 720x440)
14) Select "Precise bicubic"
15) Put a checkmark in "Expand frame and letterbox image"
16) Set "frame width" and "frame height" to the ORIGINAL dimensions (e.g. 720x480)
17) Click on "OK" (brings you back to primary "Filters" screen" and then click on "OK" (to get back to main VirtualDub screen)
18) From the "File" dropdown menu, select "Save AVI" and save with a NEW filename

Let us know of your success ;>}

A hex editor? Yes it's technically possible if you're a masochist, have plenty of spare time and an intimate knowledge of what you are doing.

A alternative to Seta_rips method if you have softsubs, is to download avi_mux_gui: http://www.alexander-noe.com/video/amg/

Just drag in your current avi file, select it in the top window and press the "generate data sources from file" button. Then it will show all the streams in the bottom window, just delesect what you don't want and press "start", then choose your filename and it will create it.

If you want to extract the subs rather than remove them, right click the subs stream in the bottom window instead of deselecting them and and choose "Save as text".
