Re: bugreport (3 bugs)

Hi.

I just download your video from
ftp://ftp.unob.cz/pub/testcases/dvdauthor/  and use ffmpeg to remux
like this:

ffmpeg -i T.mpg -target ntsc-dvd -y T1.mpg

And then create a dvd (structure and TOC)

dvdauthor -o dvd -f T1.mpg
dvdauthor -o dvd -T

All that works fine to me, just remux with ffmpeg.

Best regards,

Jorge Martinez S.
