Add anamorphic flag without re-encoding?

[mitchfx]

Is there any tool/util out there that would allow me to add an "anamorphic widescreen flag" to a title that has already been encoded without recompressing the entire thing? I have a dvd recorder that doesn't allow you to force this setting on recordings, so what I'd like to do is rip each completed disc to my computer then somehow add the proper flag and then burn back to a new dvd. Not sure if this is even possible, but hoping that you can somehow append the correct data to the VOB or other files.

Thanks,
M
