streeming to pc

In openwebif there should be two tv icons which you can click on, click on the one that has the blue screen.... the other by default will try to stream through port 8002.

VLC works for streaming to a pc with no problems, when you open it click on the preferences tab at the top of the screen, just check that the file types you are trying to open are selected....

This might be of help: to show you the webif
HOW TO: Streaming from your DVB lan receiver to Vu+ Ultimo wifi in home network

Is your stb on (on an encrypted channel) when trying to stream another encrypted one?
I'd imagine it should work, especially if a fta channel can be streamed.
There is a known problem with cccam decrypting two channels at the same time using new image releases.
The fix is to upgrade cccam to at least 2.3.0 or use oscam. Not too sure about mgcamd though.
You could also put your receiver into standby before trying to stream an encrypted one to see if it works. (will determine that it may be emu related)
This should still stream while receiver is in standby. (does on blackhole 2.0.9.1)
