don't use codec packs. Or at least just one.
2. [90][121]/W poprzednim odcinku:
this line is displayed starting frame 90 to frame 121 (about 1 sec)
[180][202]Zaatakowano Ziemię. - 1 sec.
[203][217]Mamy wracać.
this line starts just after the 2nd one (1 frame interval=about 0.05 sec) and stay about half sec on display. This is how this subtitle was made.
[218][241]Sondę wysłali Xindi. - 1 sec.
Don't know nothing about [], but if you change to {}you'll have a MicroDVD standard subtitle. So, line 3 and 4 can be merged and you get:
{180}{217}- Zaatakowano Ziemię|- Mamy wracać. - stay about 2 sec on display and can be read. You can do even {180}{210} to have a small gap till next line.
