TCPMP/streaming media question

[Incubated]

i downloaded tcp mp with the plugin from xda, but i am having hard time using it. I want to watch some videos online but when i get on the site it asks me to save them first. Is this inevitable, or am i jst screwing up. I went to settings, check more file associatons, and html box, but nothing. I just want to stream media, watch stuff online other than youtube.
Any help? With opera when i press open, it stil wants to save it first.
