Perfect - yes the openrtsp.exe was able to open the stream from the camera on the alternate port without any problem at all. I went ahead and added the -t to the proxy stream and tried again in VLC and it immediately opened. I was worried because my receiver/decoder (providing HDSDI output with genlock) is actually VLC based. This works a treat! Thanks for your help!
