Not to sound like a tool or a stooge but given the experiences you have related, the first thing in my mind was what about the cable?
I own a stream too, big deal. I have never gotten the impression that, that means anything in EFI Live's eyes/mind/forum beyond what a user/ customer that only has the most elementry of EFI Live product. You don't have to pass a test or anything just, pay for it.
Ok, I am not calling you out on this....you decided to make this matter public.
I will say publicly that I do have some constructive critisim of the V2 with regard to the cables; Both cables (To laptop and to Data port from the V2) are prone to becoming unseated, as they donot have a positive locking mechanism, which can cause weird stuff like what has been described in this thread all too often in my expirence.
Fortuneatly, my 17+ years with working on US Navy Fighter planes has taught me to be overly suspicious of intermitent connections.
Throwing out the "Competition" comment only reinforces my belief that if you can make it work with something else then, you should be able to make it work with Live.
Wether you intended it or not; I interpreted this post as a flame or threat,(take it for what it's worth) which IMHO is totally uncalled for as I feel that this site/product is the best out there as far as communication btw members/ members/ company sharing ideas/knowledge.
And with that blowhard rant, I still would like to offer any further help as a fellow EFI Live member/customer.
