OK, I solved the problem I was having with Ver 1.0 on at least on of my computers by installing the codecs suggest in this posting;

But I still don't have the foggiest idea "what" cured the problem.
It would be great if someone who understood the various codecs could pull together a single codec installation package that would help those of us that are just blindly following cookie crumb trails & hoping we find the correct set.
Now that Ver 1 is working, I am back to loving BSPlayer!
