https://forum.team-mediaportal.com/...6/dvb-subs-teletext-subs-framedropping-78418/
It is not my case, I have subs switched of at TV section
I start to be little bit desperated. Yesterday I installed new HD5450 to test hw acceleration of H.264, but again the same sympthoms: after while HDTV starts to stutter. So now there is no way how to watch HDTV properly in my case, sooner or later it starts to stutter no matter if sw codec (CoreAVC2.0) or hw acc. codec (MPC, Cyberlink 9 ) is used (situation is now even worse then with MP1.0.2).
Have you tried with directshowhelper.dll provided in that thread ?

now i'm almost happy with the 3rd one and i could put down the frequencies of my 4670 until 300MHZ instead of stock 750...... it let me use that card with the fan at 3% and it made my htpc very very quiet
I hope you can find a solution soon for you problem........
PS: please pay attention that the 5450 ins't able to decode any H.264 stream with all postprocessing and deinterlacing ON . check here AnandTech: AMD?s Radeon HD 5450: The Next Step In HTPC Video Cards
