Again: why do you need to use object variables AT ALL? This still looks like 
cargo cult programming to me.

What is it you are concerned about? Selecting the time base, selecting the end 
time or both?

As per the previous thread, VLC can already deal with start-time and end-time, 
but internally only. (The live555 plugin cannot access the end-time currently, 
so it cannot put it in the PLAY request.)
