I'm looking at a VCD 2.0-compliant MPEG that appears to have been erroneously converted to 16:9 from 4:3 source material. (The image is squashed flat.)

Any way to return the file to the proper 4:3 aspect ratio? The original is gone, and I'm aware of the likely loss in image quality when compared to a VCD that didn't have the horizontal bars inserted and deleted.

Thanks!
