I see four lines instead of movies
 

When I open any movie all that I see is several diagonal lines (4 or 5) (angle about 30) but the sound is perfect. I try both old and new version of BSPlayer. I use DivX 5.1.1 and K-Lite Codec Pack. Windows Media Player show normal picture but extremly slow.

Try different settings of overlay video mode under
(rightclick) > Options > Preferences > Video > Video rendering
E.g. give it a try with overlay mode 1 or 2 or RGB, wait for vertical blank, or Use VMR-9 (do you have direct X9 installed?) .....
:wink:
(K-Lite comes in four versions nowadays. Hopefully you did not install everything, but made good use of the possibility to be deselective. See this post)
