This is very simple in any scripting language. if you are using simple batch file then use:
Code:
for /f "tokens=1-6 delims=/:." %%a in ("%date%.%time%") do set FileName="MyShow - %%a-%%b-%%c - %%d-%%e-%%f.flv"
rtmpdump.exe -r "rtmp://live1.seeon.tv/edge/nvcrd4lz4zs0w34" -p "http://www.seeon.tv/view/11073" -W "http://www.seeon.tv/jwplayer/player.swf" --stop 3600 --live -o %FileName%
