> Rtsp is a (protocol) as the name suggests. When you want to do such things
as pauses, skip, fast-forward, etc, you have to send commands over the wire
using a handshake. I think this is quite a bit different than how mplayer
works but then ti doesn't seem that much (I don't know the code, please
pardon my ignorant response). Doesn't a seek translate to just such a
command sequence? Why would this be messy? Considering that rtsp is an
industry standard, used by (rough guess) 3/4 of all commercial streaming
sites it seems that should not be ignored.

Again, I am a developer but not an mplayer developer ...
