[vlc] Re: Multicast Streaming Problems

[Jason Simms]

I'll try this, but I did not think that I would need to enable the video 
since this is an audio-only stream.  I have balanced XLR coming into the 
Osprey; no video at all.  Thanks for the advice, though; if this doesn't 
work, maybe I will try the earlier release.
