I have no idea if thats related to the issue you are seeing, but you
should avoid the AVI container. It does not work properly for many use
cases and is super limited. (like variable birate audio streams) Try
something modern like MKV or MP4 instead.

The simplest solution would be to just re-rip the disc with makemkv or
similar to a proper container with proper metadata.
