    Poor Quality Recordings Playback

    Hi,

    I have a fresh install of Ubuntu 11.10 with MythTV and other Myth bits added. I have recorded TV and the playback quality is very poor, seems to be low resolution and a slight stutter of the picture, also the sound is out of sync. If I exit MythTV Frontend, go to the recordings folder and double click the recording it plays fine.

    What could cause this? Is there some setup that I may have got wrong?

    Thanks
    Mick

    Re: Poor Quality Recordings Playback

    I think we need a bit more information

    What recording hardware (ie tuner)?

    mediainfo output on an affected recording?

    Playback settings in mythfrontend?

    Re: Poor Quality Recordings Playback

    Mythtv can be a touchy about things, and what your system is and how it is set up is essential to doing any adjustments/tuning.

    Consider running "Hardinfo" from Ubuntu Software Center and sharing that information.

    I had never heard of 'hardinfo' before, a really good tool!

    Here is the output.

    Re: Poor Quality Recordings Playback

    Your hardware is fine.

    You should try increasing the ring buffer to maximum.

    You set an appropriate video playback profile:
    http://www.mythtv.org/wiki/Playback_...fault_settings

    Are you using High Quality transcoder?



    Are you using the HDMI output?

    Re: Poor Quality Recordings Playback

    Thanks for your suggestions -

    Increased the ring buffer to maximum. That has made a big difference, much better!

    You set an appropriate video playback profile: - That was already set to High Quality

    Are you using High Quality transcoder? Now to show my ignorance - what does that mean?

    Are you using the HDMI output? - Yes

    Many thanks for your help
    Mick

    Under TV - Setting - Gerenal - General(Jobs)

    Default decoder > High Quality

    Also TV - Settings - Playback - General Playback( 1 / 8 )

    Try enabling real-time threads ~ but read the comment on this.

    Make sure your monitor's resolution is set properly. This should happen automagically.

    Have fun...

    Surely this will only make a difference if you are transcoding - and in general, why would you?

    Also TV - Settings - Playback - General Playback( 1 / 8 )
