Here are my brand new test results. (MP: 15067 and TVE3: 15070)
First the good news: The stuttering H.264 is gone with the new tsfilesource.ax. No more need to copy over the 15008 version after updating the tv plugin.
Now the bad news

:
When I try to use the new filter with my current codec settings (PDVD 7.3 for video and FFDSHOW for audio) then I'm unable to bring H.264 to work. PAL shown only a still image and when I try to "Turn TV off" then the MP Client hangs totally and I have to close the task via the taskmanager.
The results when I use PowerDVD as audio codec are the same.
Bye
