The --enable switches override autodetection, _and_ also disable automatic setting of any required compiler/linker flags. So for most features you should let the automatic detection do its job. > Can you clarify what speed has to do with this as well? With vo=xv, I'm pretty sure he was thinking of another limitation of the svn vo driver: it can't advance frames faster than display refresh rate. However your problem description didn't match the expected symptoms and he also missed that your log output already showed 50 Hz (so basically he was on the wrong track and it's not relevant to any of the actual issues).
