    youtube suggests STW for subtitle adding, so i downloaded YT video (with help of sfrom.net service) in maximum avail resolution ( 720p mp4 ) and wanted to start...

    I tries STW 2.51, 4b1, 5b1nrv, 6b1 - none works.

    At least 5b1nrv gave some diagnostics. Actually it looks weird that 6b1 seems ot be worse than 5b1 ( no reasonable error diagnostics, failure to open files in path with cyrillics ). It looks like good patches from 5-branch were migrated to superceeding 6-branch and at the same time regressions were added ).

    Other videos like AVI and MKV were played fine ( i think MKV contained mp4, aint sure about AVI ).

    So, diag from V5

    One might say i so not have codecs installed (and actually here ATM i only have win8 built-in ones and DivX, and we all know too many codecs is a mess. But i would probably try to add ffdShow...)

    But the video is played fine by both built-in WMP and win8 "Metro" player. So codecs are present...
    Maybe STW requires some specific API version, dunno, but it was not mentioned anywhere...

    It looks somewhat weird that STW cannot work with YouTube media, while being advertised in YT, and that that problem is not addressed in FAQ explicitly. I think there might be quite a share of users, who would come from YT to try your software and would hope to see it "just work" or at least have a certain YT-centered istructions what to do

    I just tried to run 32-bit wmplayer.exe from Program Files (x86) folder and i checked in TaskManager it was of "32 bit" platform, not of "64 bit" like other tasks, and it also played the file. So there IS the codec in the system

    VLC file info:

    Кодек: H264 - MPEG-4 AVC (part 10) (avc1) 1280x720@25
    Декодированный формат: Planar 4:2:0 YUV

    Кодек: MPEG AAC Audio (mp4a) Stereo 44100Hz

    Looks rather typical

    You simply need to install a video codec pack. There's nothing else to it, no "specific APIs" required or anything. Other players like VLC and WMP have internal codecs, that's why they play the video. Subtitle Workshop doesn't have internal codecs, it relies on the system codecs. Simply install the latest version of K-Lite.

    About the differences between the versions of Subtitle Workshop -- they are substantial indeed. That's because Subtitle Workshop 6 is based on Subtitle Workshop 2.51, because that's the version that has initially been made open-source. Subtitle Workshop 4 and 5 have never been open-source and Subtitle Workshop 6 has nothing to do with them.
