Considering each subtitle replaces the previous one, what would you consider a reasonable behaviour? Silently dropping user input is not a good option.

comment:2 Changed 3 years ago by rieve

Agreed. VLC displays all entries at the same time, that seems reasonable. So I'd suggest that the behaviour is equivalent to this:

1
00:00:02,500 --> 00:00:03,000
hello
world

2
00:00:03,000 --> 00:00:06,00
world
