Cannot get any kind of video to import into 9.5 elements

I have tried to import several different formats of video into Elements 9.5 to no avail. I’ve also have Elements 7.0 and it would not import them either.
So after a lot of reading, has Steinberg done anything to correct this problem? Is there anykind of a patch or fix for it? Or is there a codec that anyone can tell me that I can convert my video to that will work?

Thanks for the help?
