Ever since updating to RC3 I'm experiencing heavy stutter and heavy artifacts on some TV channels - that all used to work with RC2. The problem is that there's no (apparent) pattern as to what TV channels work/don't work, i.e. some HD channels work, while some don't and some SD channels work, while others don't.

I haven't changed anything in terms of codecs/renderers/drivers/etc. since RC2.


Here's a list of some of the TV channels I tried and how they behave:

Not working:
  • ORF 1 HD (720p) (also has stuttering audio (usually DD 2.0 or DD 5.1))
  • ORF 2 HD (720p) (after a while)
  • HD suisse (720p)
  • ORF 2 (576i/p) (doesn't work at all, picture freezes when switching to this channel)
  • ATV (576i/p)
  • Puls 4 (576i/p)
  • Prosieben (576i/p)

Working:
  • ServusTV HD (1080i)
  • ARD HD (720p)
  • ZDF HD (720p)
  • arte HD (720p)
  • RTL (576i/p)
  • Sat.1 (576i/p)
  • Bayerisches FS (576i/p)


Note: I have only tested those channels for like a minute, so some of the channels that I listed as working here might start stuttering after a while too (like ORF 2 HD that only started stuttering after a couple of minutes).
Note: "576i/p" means that I don't know whether the channel is broadcast in 576i or 576p (is there a way to find out?)


The debug logs are from ORF 1 HD (heavy audio and video stutter).

    Hi,

    I'm not sure if this is related, but I have an issue with Discovery HD, not sure if this is since RC3 or somewhere before, as i do not watch this channel very often.
    When starting this channel it stutters (shows 1 picture every second or so) sound keeps going.

    After some time, somewhere between 10 to 40 seconds, it will play smooth.

    Client logs attached, if server logs are also required please let me know.

    I have the same problem with one danish HD channel (Kanal 5 HD), other HD channels are OK.
    Never had problems with this before.
    Went back to RC2 and problem gone (RC3 not a clean install, maby why?)

    Made a clean/fresh install of rc3, and now it seams to work.

    I just un- and reinstalled the TV server (and client) plugins and everything is back to the way it was with RC2.

    Clean install, that's weird... Maybe try a reinstall of the TV server nevertheless?

    here also heavy stutter. Almost every minute. Sometimes mediaportal will just crash (not in this log) on it.
    TSReader log has a lot of discontinuity errors. Signal quality at my dvb tuners (firedtv-c and firedtv-s) is good, I never had this much discontinuity errors before and nothing has happened to my setup.
    Under RC2 I had every 30 minutes or so one tiny stutter (maybe switch from timeshift file??) that was still acceptable. RC3 is unwatchable for me. I'm reverting to RC2 again. Logs are included

    edit:
    just did a clean install of RC3.. both tvserver(even new database) and client - same result, every 10 seconds heavy stuttering. So much that it is unwachable.

    Now reverting to RC2

    Did some more testing. I'm convinced that the stuttering is caused by the tv server. I checked this by playing the recorded ts files in VLC. The old recordings I have from RC1 don't contain stuttering. When I play them with Mediaportal RC3 everything is fine.

    Can anyone point me to a download location of the RC1? I don't have the installer anymore.
