Well, that was fruitful...
After setting the port forwarding and whatnot, I started VLC up with at nice little test clip (in the case, I used "The Trail of Fr. Kino"), and it was actually coming through to my other internet circuit and I could see action on the terminal window of the Linux box. On the Windows box, VLC even started up with 9:06 on the clip duration time.
It just didn't play.
It's frustrating in some ways, but I have to admit: We're further along than we were yesterday. This is good news in some ways. Now, I'll just have to get into the forums and figure out why...
Stay tuned! We'll get this up and going yet!
