That's the 1st I've seen of it. And yes it doesn't seem to have any accuracy at all. I'm also ignorant as to how it should be used. I applied 500 MB & the 2nd search 50 MB & it didn't seem to make any difference. I don''t normally dwnld movies which is why I hadn't seen it before. It could be a simple trial. If it is it's not a highly succesful one unless as you suggest there's a technique to using it.
