Freezes at opening or skipping inside mp4 and mkv files on XP Pro 32bit SP3 Romanian

[rooster]

BS.Player PRO version 2.66 Build 1075 and several before it.

When opening or skipping inside mp4 and mkv files BS.Player freezes at random, very annoying.

Tested on several computers of mine with different hardware configurations, all XP Pro 32bit SP3 machines. Windows has all updates from Microsoft, standards are Romanian, location is Romania, language pack is romanian (LIPSETUP_XP_SP2_ro_29.11.2005.MSI) - therefore BS.Player is installed with default Romanian language. There are no codecs other those BS.Player self downloaded and installed.
All I have modified is the skin to BSplayer.v1 and disabled automatic upload of subtitles. Also when installing I choosed to save settings in instalation folder.

The problem does not appear with avi files (divx).

When it freezes it can be quick closed only from Task Manager, or if I wait enough it can be closed fron task bar too, but in tray area there are remaining up to 3 icons: FFA, FFV and BS witch are dissapearing after hovering with mouse over them.
bugreport.txt does not record information, but I will attach 3 logs from 3 computers where this problem appear - logs are generated from an subtitle error (I presume) that I will report too.
