Media Centre 7 Live TV audio stutter

    שאלה

  • Hi all

    Ive been having troubles with my HTPC and any Freeview broadcast.

    Im not too sure if its the broadcast, a hardware or codec problem.

    When watching Freeview (any program, on any channel) the audio starts to stutter and eventually goes silent (quite frequently). In order to get the sound back I have to pause it and play again.

    This only happens when watching live TV, but does not happen on recorded or chase play TV.

    I have also pressed record while stutter occurs and recording is perfect, even thou the stutter has progressed in to silence.

    The problems started when I was forced to upgrade my hardware as what I believe the PCI-E slot failed.

    Both systems are running Windows 7 Ultimate 64bit and inbuilt Windows Media Center

    My upgraded setup is:
    - Intel i3-2100 3.1ghz processor
    - Asus P8H61-M Pro motherboard
    - 1 x 4gb Ram
    - 550w PSU
    - CoreAVC for MKV playback
    - Clean install of Windows 7 Ultimate 64bit
    - WPI of 4.9

    Carry over components from previous system:
    - Geforce 210 video card 512mb
    - OEM SATA 160gb hard drive
    - 2 x USB tv tuner sticks (AverTV a825 and PCTV 73e) to receive Freeview (3 x tuners)
    - USB IR receiver
    - OEM Compaq SR1925 case

    When watching Freeview HD CPU usage is no more than 10%

    My previous was a Compaq SR1925 home PC and have upgraded it with:

    - Athlon 64 X2 3800+ processor
    - 1 x 512mb, 1 x 2gb, totaling 3gb Ram
    - 2nd 320gb hard drive
    - CoreAVC for MKV playback
    - WPI 3.8

    Other components in my system are:
    - Sony 40" LCD TV (connected via HDMI)
    - Pioneer VSX915 amp (connected via digital coaxial(old system) / optical (new system))
    - Harmony One remote

    Things I have tried:

    -Using drives provided by Windows update, and failing that the latest drivers from the manufacturers site.

    -Attempting to change the audio codec to 3rd party codec

    -Using 32bit and 64bit Windows 7

    -Outputting audio to TV Via HDMI, then using stereo RCA to Amp

    -Installed Mediaportal (worked without any problems so should rule out broadcast issue)

    Thanks in advance

  • Hi All

    I found the answer to my problem.

    In the registry I increased the Pre Pool Buffer to double the default and followed the instructions posted by "corego" on this forum.

    Thanks for the input.
