I was looking for something that worked properly every time.
There is no such product.
I bet you may wonder why so let's get that up on the table. It has to do a lot with copyrights. For example let's use FLASH as an example. If I had a FLASH video then Adobe has the license on that encoding and decoding. If I included that, Adobe may want a fee for the feature I'm using.
There is VLC Player that plays just about everything but if you examine how they are able to get away from the license issues you find that their country does not recognize such patents or licenses.
I know folk are a little upset about this mess.
