I have never used them and never will. First and foremost, there is no such thing as "unlimited." No body can truly offer you unlimited space or unlimited bandwidth as everyting has limits. Any self respecting hosting company that offers an "unlimited" anything will have a bunch of stuff in their terms talking about everything is based upon fair share. The minute you exceed what would be considered "fair," they can and will terminate your account. Secondly, HostFLV is run by a script company. Nothing further should need to be stated.. but... Three, they are using iWeb for their hosting services. iWeb, claims to offer unlimited space hosting. However, their terms have a bunch of limits as to what you can upload and how big they can be. Most video sites will not fit the bill.
