CDRWin and CDRWin

Why are there 2 versions of CDRWin?
There’s one from (latest version 3.9E) and another from (latest version 5.0).

I suppose the one from is the original one.
But why is there another one with the same name (CDRWin) and same company name (GoldenHawk)?

I also don’t see any kind of support for version 5.0.

What are the differences between the 2? And is the 5.0 version any good compared with others like Nero, BlindWrite or Alcohol?

This is simply a matter of one company ( stealing a name from a reputable company ( to release a crap piece of software and confuse people like yourself.
