FLV... which doesn't use flashplayer - but also does NOT show all 4 feeds off to the side (I like seeing them)
For less CPU/BW usage, resizable/fullscreen feed experience try my BB12 FLV Launcher!!!!
If you want to put Superpass's player in a window try BB12 Viewer experimental viewer
I'm trying this one out - you can "capture" images with this one. But I think it still uses Flash
so - now I have 3, lol
