Wrong aspect ratio of DV files on MacOS

[bidspells]

Dear Dan,

the grabbed DV (also AVI) files have a wrong aspect ratio when viewed on MacOS, it is 4:3 rather than 16:9. On Linux the aspect ratio is fine.

It tried dvgrab 3.4 and I rebuild dvgrab from sources. Same behavior.

I observed that "transcoding" a dv file to a dv file using FFmpeg solves the issue (but the Creation Time get's lost): ffmpeg -i in.dv out.dv

Do you have any ideas to solve the issue (instead of "transcoding" and loosing metadata)?

Thanks for still maintaining this highly useful piece of software!

Best regards, Erik
