I'd like to add another vote for updating the UI so when a file is added, the UI would automatically set the delay. This example is a file created with DGIndex, but I guess it can be smart enough to look at a format of "DELAY xxxms" in any file.
Code:
Some.Movie_OAR_1080i_dd5.1 PID 014 T01 3_2ch 384Kbps DELAY -376ms.ac3
Thanks for considering it. Btw, is the source available for 1.3.0.0? Thank you.
