Hi all,

since today I am experiencing issues when playing some video files. every couple of seconds the video stutters and hangs for a split second. I havent changed anything on my system configuration or driver or codec setup and until yesterday everything was running just fine. I did a reboot a couple of times, but this didnt help either. Also it doesnt happen on all files, and not all the time. Sometime a file is running just fine, and the next time it is suttering. I cant seem to make out a pattern.
I have checked my mediaportal.log and found these lines which seem to be consistent with the video hangings:

Can someone explain, what is happening here? Can this be the cause of the stuttering video and what can I do to resolve this issue?

Hi Merlyn

It might be an audio codec problem. Your preferences show that you want to use the MPC-MPA codec but in actual fact it looks like the FFDShow codec is being used. Please try a different audio codec.

Thanks mm.

ffdshow was set as audio filter. Tried switching audio codecs to MPC, but to no avail. Installing LAV 0.33 filters helped, though.

Still wondering, what this log entry is about...

Hi again

The log entry is completely normal. My understanding is that it is related to the presentation of the video and/or textures. If you didn't have that then I'd be worried.
