flv videos only play with OVERLAY MIXING RENDER. why?

[alejandro]

Hi, I have the skp 2.0.21 and would like to explain to me RENDER VIDEO options, as there are FLV videos that plays only when in OVERLAY MIXING RENDER.
Previously was working with the skp 2.0.17, windows xp, k-lite codec 7.0.0 full, VIDEO MIXING THE RENDER 9 and I had no objection.
Now work with skp 2.0.21, windows 7, k-lite codec Mega 10.0.5. I try changing the version of k-lite but still has problem with flv videos.
Therefore I would like to know more about the RENDER VIDEO option, and if the RENDER MIXING OVERLAY work I will not have problems in presentations of karaoke and videos.

Regards.

i had a similar issue with renderer 7, if klite is installed it does not work, but if i uninstalled it, then the renderer works fine. maybe try uninstalling klite, it seems to be conflicting somehow with the power codec pack.
