HDTV pixeling and jumps seconds back... (1 Viewer)

[nachttier]

Hello,

I was on the verge of submitting a bug report but just found this thread so I decided to post my findings here first.
I can also see such a pixelation effect on my nVidia card, running on Vista. So an ATI/W7-only bug can be ruled out.
Even worse: although it does not always happen, I often can provoke the error by doing the following:

1. Exit MP if not already done
2. Start MP and enter live TV, starting with one of the affected channels (i.e. 720p H.264)
3. Call Mini-EPG -> notice the picture stopping for ~2sec, probably loading some graphics/EPG stuff into memory
4. Close the Mini-EPG and see the pixelation (actually it is already visible as soon as the Mini-EPG has loaded and the video continues in the background)
(5. fix the problem by jumping to another point in the timeshift buffer - usually error won't come back)

This are also the steps I did for recording the folling demo:
YouTube - 720p pixelation

I also attached the logs of that demo (MP in debug mode).

If I had to make a guess, I would say that as soon as the Mini-EPG is loaded, obviously quite a lot gets stalled. This causes the directShow graph to get out of sync/stumble and then it does not recover. Why this (for me) only happens on the 720p channels is beyond me.

Kind regards,
nachttier

And that looks for me not like an ATI Bug in general. In DVBviewer the pixelation problem never occurs to me. So i guess it's an specific Mediopartal Bug with Ati Cards.

Hello

I have the same Problem. But i used a Server2008R2 System with the same Effects. HD & SD Artefacts after some Minutes. SD works better then HD. I test it on 3 Clients.
When i put the TV Card in the HTPC-Client, all works Fine! 49FPS per Seconds.

The Graph stops too! That is strange, as if the application stops an not the Stream.

But i found now the Problem. VMware with SBS2008 was installed on the ServerR2 Server too. When i deactivate the VMWARE-Serivce it works. I think there was too mutch HD Traffic.

Any news on this?
I have the same prob (2003, ATI, good signal strength, mostly on HD channels)
