Aspect ratio corrections?

[Weirdo]

Hello, 2 problems follow:

1. I have an original, badly authored dvd-9, with a 4:3 letterboxed film. The picture is pretty much 16:9 but horizontally squeezed. It probably needs an aspect ratio change to 2.35:1 or similar. Is there a way to do this, possibly without re-encoding?

2. Is there a way to convert a 4:3 letterboxed dvd-5 (even film-only, without the menus) to proper 16:9? I've done this with DVD-Rebuilder but it only works with dvd-9, since re-encoding is required.

Thanks

Probably the aspect ratio should be changed from 4:3 to 16:9. Open the disc in PgcEdit and adjust the attribute of the main title. No re-encoding is necessary.

Players ignore a.r. flags. It must be done via .ifo's like BigConder pointed

A player would but a DVD authoring tool wouldn't.

Thanks, for the first problem, I tried changing the aspect ratio to 16:9 but the resulting image is, although anamorphic widescreen, still horizontally squeezed. I can only watch the correctly sized image with various software dvd players, disabling the "fixed aspect ratio" option, an adjusting the video window properly, but I have no idea on how to achieve that properly on the VIDEO_TS folder.

Worked around the 2nd problem: Created an oversized dvd-9 with DVD Lab, containing the aforementioned 4:3 letterboxed film, plus another one (16:9 anamorphic), then encoding it back to dvd-9 with DVD Rebuilder, converting in the process the 4:3 film to 16:9 with the AVIsynth options.

Still not a clue for the 1st problem though.
