Discovered a new issue that pops up intermittently.
If a pre-title movie is watched in full and followed by the title movie without any input from the player (e.g. pressing OK to skip to the title screen), sometimes the audio of the pre-title movie will continue to play alongside the audio of the title movie, instead of properly being canceled (i.e. stop playing) when the title movie begins playing (and its audio begins).
To replicate this bug, simply have both a title movie and pre-title movie with their own audio, and watch the entire pre-title movie with no input. This bug does not always occur, but will occur from time to time.
Here is a bug report from a user and how they were able to trigger the bug (a little different method, and still does not always trigger):
"Sat through entire title movie audio track until looped back, then booted up game again; then pressed a button to skip pre-title movie once I lingered on the pre-title movie a bit; then after on the title screen a bit, closed game and booted up game again; then sat through pre-title movie and it replayed the pre-title audio track while on the main title screen, at the same time the pre-title audio played."
I want to point out that the audio for the pre-title movie is part of the pre-title video itself, the plugin itself doesn't have an audio section. While the audio for the title movie is the audio setup to play in the system section of the database; the title movie itself does not have audio.
