Hello,

time to time there is a big stuttering during playback of HD channels. Zap to other channel and back solves the problem. TS reader log is full of such lines:

I remember I had similiar problem in MP 1.0.2 when Cyberlink H.264 codec was used, when I switched to CoreAVC 1.9.5/2.0 it was solved. Now the problem occures in MP 1.1 RC1 again even I am using CoreAVC 2.0.

I was seeing something very similar. I just found that setting "Keep MediaPortal always on top" under General in Mediaportal Configuration seems to have helped greatly.

Thanks for hint, but I took a look into the config and the flag is set there, so the problem must be somewhere else...

i've put the old directshowhelper.dll from 6th feb svn 22975 and magically the stuttering has gone...almost all (just 7 frames dropped in 30 min of 1080i tv watching). I think something went wrong with the directshow and RC1 version.
Can you confirm this behavior ?

Hmm. I know there was a vote on which dshowhelper to use and after sometime the popular one was committed and released with RC1 (IIRC):

If possible, try those out and report your findings in that thread.

Hey that is a really good poll, thank you

i'm going to test all the 4 dlls and i'll post the results

What i can't undestand is why a so useful poll was not put on the homepage of Mediaportal to make it more visible and to get many and many more testers doing it.
I totally missed it , i 'm very sorry for that.

byeeeee

I tested dshowhelper.dll from SVN 02-06-2010, but the same behavior (time to time TV starts to stutter, changing channel or skipping back+forward fix it).

I've got the exact same problem that sometimes occurs...

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).
