Issues Converting VOB files after update

[savathuntechquestion]

Hi after the new update on Windows 11 I'm having issues converting VOB files, in the past I converted them to .mp4 but now it throws an error (posted below) and the program recommends I convert them to mpeg but then there is no audio. The original VOB files play and sound fine. My goal in using Losslesscut is to convert and stitch together VOB files into 1 mp4 file for Plex with as little quality loss as possible.

The export settings I'm using:
Enable MOV Faststart (enabled)
Preserve all MP4/MOV metadata (conversion fails to MP4 whether enabled or disabled)
"avoid_negative_ts" (make zero option)
"ffmpeg" experimental flag (disabled)

Error: Command failed with exit code 1: D:\LosslessCut-win-x64\resources\ffmpeg.exe -hide_banner -i D:\In Progress Musicals\DVD Video\DVD Video\VTS_01_1 (7).VOB -map 0:1 -c:0 copy -map 0:2 -c:1 copy -map_metadata 0 -movflags +faststart -default_mode infer_no_subs -ignore_unknown -f mp4 -y D:\In Progress Musicals\DVD Video\VTS_01_1 (7)-00.00.00.000-00.24.35.007.mp4

hi. your vob file contains an audio track that is of type pcm_dvd. Losslesscut/ffmpeg is not able to mux this into a mp4 format. If you choose mpeg or mpegts as output format, maybe it works? i will add support in the next version so that when exporting to MOV format, losslesscut will automatically convert from pcm_dvd to a supported pcm codec (note that mp4 cannot handle pcm at all)

Thanks for the explanation and converting to mpeg didn't throw an error but the file still has no audio. I appreciate the effort for next release, your program has helped me convert a lot of multipart VOB files into a single file for plex.
