Hello again
MarcelV
I noticed you apparently edited your initial post and now added even a fifth line (www.bsplayer.org) to it (so that my first response to your post could perhaps seem to miss the point)
To come back to your question: BSPlayer will indeed only show max. 3 lines (I tried it with .srt subtitles which I use in 99 % of all subs).
In The Netherlands movies are almost never dubbed, but subtitling them is, for all practical purposes, the near 100% standard. We really are a "subtitling country". The overwhelming majority of subtitles are 1 or 2 lines. I've come accross a subtitle file with 3 lines only very exceptionwise (and I've quite a few!!). Sofar I've never seen any subtitlefile with 4 lines. So for normal everyday's practice even 3 lines is almost "overkill", let alone 4 lines. So I can imagine BSPlayer indeed only shows max. 3 as you have to draw the line somewhere!
