Don't think VLC can be utilized by Orb, but if so that's not a bad choice,
I've just started using Quicktime and it almost never needs to buffer for some reason... haven't used it for long but so far so good,,,
On your Orb account 'settings', you can set Quicktime to stream your video/TV.....give it a try and let us know...
BTW, if I remember correctly, I think I have Quicktime version 7....it's free to download if you already don't have it on your laptop.
