[Red5] mp3s on trunk

[Alien8 Recordings]

Wow!! That was quick. Yes, the time is displaying fine right now. The  
buffering is working much better now as well.

The only thing is that when I pause or seek it takes some time for  
the buffer to fill before the audio can start playing. It used to  
happen much quicker with 0.4. I suppose it could be a network issue  
but maybe not. Anyway, once the buffer gets filled it stays that  
way... that's the main thing.

Thanks so much for super quick fix!

Take care,
Sean
