I don't know when OpenBSD will get the latest release of VLC (The new Qt version), but according to the
release notes there was some work in this regard..
"RealVideo support (with the RealVideo run-time)"
The mention of a "run-time" concerns me, not sure what that entails..
There is something called "Helix Player" for Linux.. I'm unaware of any porting efforts, or if it's even possible.
