Please DO NOT BUY the Dazzle Hollywood Bridge! I made the unfortunate mistake of doing so and it is the worst purchase I ever made. The thing often loses vertical sync, sound distortions occur frequently and unexpectedly - in other words, a complete piece of unreliable garbage.
And, no, it wasn't a dud model either. I casn't tell you how many forums I've been to where all of the poor Dazzle dupes like me gathered to lick our wounds.
If you want the worst customer service and support you'll ever see, deal with Dazzle. They took no phone calls, actively discouraged any email inquiries and offered only a message board (in which no Dazzle representative even responded to). Now get this - once the message board was packed full of endless complaints, Dazzle simply deleted the thing and stopped hosting it.
I finally stopped using this thing but still have it stuck in a drawer. I thought of selling it on eBay, but would feel horrible sticking someone with it, even if they only paid $10 for it.
The Formac (which I use now) is a great choice. It actually works, for one thing ...
