There are a couple of video streams GroovyVid offers. One is the RetroEDU stream http://126.96.36.199:8888;stream.nsv
This stream was working for me at one time, but has not for several versions now and I cannot figure out why.
They also offer a MST3k streamhttp://188.8.131.52:8010;stream.nsv
I use the Movies-VLC-FFMPEG profile for that stream and it works. Using that profile for the RetroEDU stream does not work. When I select 'test transcoding' two DOS boxes pop up and are closed very quickly so I cannot read what's going on.
How can I get this stream working again?
