It's 25 FPS.
I've seen problems like this in some situations and haven't managed to
pin it down. When this happened on minimyth I managed to solve it by
ensuring that mythfrontend ran as an unprivileged user rather than root.
I still don't understand why that worked.
That may not be the problem in your case. I suspect that this has
something to do with the data rate and buffering in the front end. The
bit rate of a normal TV video+audio stream is substantially higher than
that of a radio+fake video stream and when I've seen stuttering it
usually seems to be accompanied by prebuffering pauses in the log.
