Some videos play in slow motion, many of them have AV out of sync etc. It just never seems to just work.

Now that a paid version is out, I have a lot of bones with it. For one, getting the dang thing to work at all is such a major headache no matter what computer I install it on, it requires the use of 3rd party plugins that are ancient to even run. It seems more like some hobby project than anything else, even in version 4. Why would I pay for a major headache of configuration issues that I have literally poured countless hours into trying to solve?
