If your looking to just watch tv and dont care about the complexities behind the scenes then a STB is by far the easiest route. If your like me and find the complexities the interesting part, and want to know every behind the scenes detail then STB's are a waste and PC tuners are king. I'll have to look into adding failed lock tp's into my blindscanning portion of updateDVB, I had never thought of it before this thread but can see that being a valuable resource.
