Yeah, sourcetv is a bit fucked up right now. I worked one week before the tourney with ILL on the problems of source tv, but we couldn't fix it. it could be a bug in the mod code, or valve just broke everything again.
As for the different view angles. When you see only the feet the AI-Director moves the cam. Spectators on the hl2ctf server should be able to control the cam aswell for the viewers on sourcetv, by pressing the use button in spectator mode. Unfortunelly it doesn't work either.
When you are able to choose the camera angles yourself as spectator on sourcetv, the sourcetv server is in a special mode wich eats 1/3 more bandwidth. I'll try if the server still runs fine in this mode, so the sourcetv spectators can watch it better. (Of course only if that works, wich would be the 1. thing that works

)
