VLC skips few seconds when recording in h264

Hello,
I try to record a video from a DVD, which works almost fine...but if I use h264, there is a small "jump" in the very beginning (after about 3-4 sec) for about 2 seconds. And it is reproducable. Also with other DVDs. If I take h265 its gone, but then when i start the video, the standard resolution is 4:3 instead of 16:9 which is not correct...and its annoying to have to change it always manually.

Any idea, how to fix?

Thats the script code I use:
"C:/Program Files/VLC/vlc.exe" dvd:///F:/ --sout="#transcode{vcodec=h264,acodec=mpga,ab=128,channels=2,samplerate=44100,scodec=none}:std{access=file,mux=ts,dst=D:/VIDEOS/video.mp4}" --no-sout-all --audio-track=1 --audio-track-id=-1 --noloop --start-time=1 --run-time=2544 vlc://quit

Thanks.

Try with --start-time=0

This unfortunately did not help. It runs for 5 seconds in the beginning and then skips 2-3 seconds and then run normally until the end....strange.

Hello!
Could you share the verbose log output in a pastebin? Add `-vv` to the command line.

The full debug log is too big for that window....can I somehow attach a file?

Happens to me as well on version 3.0.18
Any fix planned?
