So about recording with source tv (stv). Correct me if I'm wrong, but it seem pretty simple:
First you need to enable stv by doing this command in console:
tv_enable 1
Now you should have a spectator on your server called source-tv or something like that. If you don't, try to switch map and then see if it's there. When you got your spectator you want to record your demo, with this command: tv_record name. To stop your recording, do this command: tv_stoprecord. More info
here.
And now my double skip on badwater again. Also, jump start at tick 5200 aprox.
