Sorry to maybe introduce a new topic in this thread... or not...
I've got this kind of log every second for some of my regular OPEN DVB-t channels:
What do they mean? As you can see, they appear at a regular rate of around 600 ms...
I've found this while trying to troubleshoot a strange problem that I would describe as weak signal (artifacts in video, reverb repeated audio frames, that sometimes leads in MediaPortal UI restart) in some channels... BUT it's definetely nothing to do with signal strengh, as I don't see problems analyzing live ts with some tools (TransEdit inside DVBViewer for example). I can watch that channels in DVBViewer, in fact. Some other data:
- it only affects HD channels. SD are OK.
- It's quite random. I can watch TV with no problem for days, and then, suddenly, it starts happening, then it cures itself.
- I've been able to reproduce the problem also in HD DVB-s channels. So definetely not a signal problem, also tvcards seem not guilty.
- I've been suffering this from 1.1.0. I can't remember to have changed anything in my system when it started to happen.
- I can see the log you can see above always, even when no artifacts... I just put it there in case it helps, but it maybe have nothing to do with the artifacts
- No strange log in tswriter.log.
- I've tried Cyberlink PowerDVD 11 and Lav Video last month or so, same artifacts...
- I'll try to post tsreader log next time it happens, but as every time you start MP, tsreader for that day is overwriten, it's been hard to get...
If I should open a new thread please tell me and I'll do so.
Thanks a lot.
EDIT: FORGET about all the above. I've been able to troubleshoot it in more detail this afternoon, as the problem has appeared quite often... and I can see I've got this problems with virtually ANYTHING I do in my PC. Sometimes my PC just "hangs" itsef for some seconds... , same HTPC that has been working OK for more than 2 years...
Now... how could I find the source of the problem? It will be hard and take time that I don't have...
Thanks again.
