As predicted, another TV provider has moved from WMV to Flash. This time it's Channel 4 who switched over on the 1st April. When I read about it, I thought perhaps it was a poor April Fool's joke, but of course it wasn't.
Version 2.7.0 of TunerFreeMCE provides support for the new flash content for Channel 4, and the good news is that it is really fast to parse and provides reliable streams. It also allows me to split out in to Channel 4, E4 and More4 again, and to get better broadcast date information. The bad news is that it isn't too reliable at going full screen. I am hoping that C4 stabilize their screens a bit to allow me to make going full screen more reliable soon.
