BSPlayer needs codecs (filters) to be installed onto your system. If you read the very first post you will find out that and where to find every codec you need.
So, you can do what Tizio suggest, uninstall codec pack and let BSPlayer codec manager install the codecs needed (I personally don't recommend that because I saw many computers going nuts after uninstalling a codec pack) or install RealAlternative to play MOV files.

I just read the K-Lite changelog and seen that the bad version is the one before 4.45 (nothing wrong with 4.45 and 4.53)

For the "What is wrong with 4.5.5?" question... well, the answer is that: it has not been released yet ;)

As my phones record in 3gp format with AMR (and I am not a fan of ffdshow), I was looking for an AMR decoder. So, finally I found one. Working ok.

Hi, does anyone have a SAFE place to get a codec to decode x265 coded files? Where?
I am running bsplayer 2.76, build 1090.
Any other software needed other than the out-of-the-box set-up?

LAV filters should be enough.
