Upgrading from 1.2.3 to 1.4 - now have jitter & tearing (1 Viewer)

[-=Is0metric=-]

Hi KeithP,
This may or may not help...
I have recently fixed (today) a horrible problem where I was getting tearing in both live TV, recordings and worse still, mkvs.
You probably already know, but tearing is the where the top half of a frame looks offset to the bottom. Obvious during panning.
Anyway, after a few hours of tweaking, updating drivers with no effect, after googling I found a mention on AVS Forums.
MediaPortal requires Aero to be functional.
Therefore you should have Vista or better, Aero enabled and uninstall any mirror display driver (this disables Aero)
I had recently installed a mirror display driver (dfmirage) for use with TightVNC. I removed it and bazinga! All now works as expected.

Of course, this might not be related.
Best of luck
Iso

I am not sure what happened last night, but in fiddling around getting my system specs and tweaking etc. I seem to have inadvertently fixed my playback issues, having failed to fix them for the previous week. Annoying because I would have liked to know the root cause in case it happens in the future! But it is working so I am not touching it again.

Thank you to all who pitched in to help.

Same problem here with stuttering and jitter under XP-SP3.
With upgrade from MP 1.3 to 1.4, heavy stuttering and jitter, but only after 'resume from standby'.
Then restart of MP and everything is perfect again.

Reverted to 1.3 and everything is fine. There is surely something broken with video in 1.4.

You should try this patch: https://forum.team-mediaportal.com/...les-is-corrupted-with-1-4-0-pre-in-xp.119713/ .. or upgrade to MP 1.5.0 Pre-Release.

EDIT:
I see you are already tested the patch...

Hello Gerd

If you experience problems with MP 1.4 on XP then I think you're probably best to stick with MP 1.3. I don't see this problem, but then I don't use standby/hibernate + resume. Realistically even if you were to provide log files and I was to find and fix the problem there is very little chance of another XP-specific fix going into MP 1.5. After MP 1.5 it is looking like MP will be completely incompatible with XP...

I am experiencing Jitter after resume using XP and 1.4 - here's my thread on the subject
https://forum.team-mediaportal.com/threads/stutter-after-resume.120601/

My fix is to have firefox running in the background - no more stuttering even after resume. I haven't dared try 1.5.

Exactly the same comments as for Gerd.

Use the patch as recommended by Holzi (which is included as standard in MP 1.5 - so actually MP 1.5 will be better than MP 1.4 for XP) and if you still have problems, go back to MP 1.3.

I note that you have strange codec issues going on in the log files posted in the other thread.
You've configured to use LAV, but actually the codecs being used are:

24-07-2013 00:53:03.906 [192f0048] [ c28] audPin:CompleteConnect() ok, filter: ffdshow Audio Decoder
24-07-2013 00:53:04.015 [192f0048] [ c28] vidPin:CompleteConnect() ok, filter: NVIDIA Video Decoder

That could be part of the problem.
