Wrong, it is on WGT's end ;-) I am web apps developer with almost 20 years experience and I see exactly, what traffic WGT's servers are generating and that it is complete mess in the case of this video carousel (it is very easy to sniff and analyze).
And as a skilled web developer I can say, that problems can have only some clients (I am not the only one, read other therads on this forum), while other clients can be completely ok. There are many things, that can cause problems, and it is application' owner/developer responsibility to find and solve the problems, not user's...
Our business would quit very fast, If ve had the same customer support quality as the WGT has...
