Audo/Video sync issue

[zkirkpatrick]

I am trying to play 720p rips of Jeopardy from a Windows x64 installation of Jellyfin (v10.8.13).  These files lose audio/video sync within the first minute of playback.  I used to be able to acquire HDTV (lower quality) rips of these files which played perfectly, but don't seem to be available anymore.  I'm sure that Jellyfin supports these higher quality files, but are likely being encoded in such a way that my server doesn't like it.[/color]

I've played with some of the settings in the Roku app referring to various playback and audio settings, but cant seem to bingo one to help.

Windows x64
Jellyfin 10.8.13
Roku playback
Filetype: MKV
File details: x264.AC3
File Resolution: 720p
File size: ~400mb
