Tuning Video Output

Setup There are two recommended settings to optimise video output. The best setting can vary depending on display hardware, and customers own individual preference.

Optimal Setting with XvMC

We feel this is currently the most optimal setting for general video output. Make sure you have downloaded the most current patches and fixes before applying these settings.

You can place myPVR in this mode as follows.

Go to the main myPVR menu by pressing ether
TV Settings

  • xthe green button on the remote control, or
  • Ctrl+Alt+Enter on the keyboard.

Then select the following menu path

  • Utilities/Setup
    • Setup
      • TV Settings
        • Playback

Set the fields on the screen to match the screenshot to the right as follows. Use Left/Right on your remote to change values, and OK on your remote to enable/disable settings.
General Playback

  • Enable – Deinterlace Playback
  • Algorithm – Kernel (less Motion Blur)
  • Custom Filters leave blank
  • Preferred MPEG2 Decoder – Standard XVMC
  • Disable – OpenGL vertical sync for timing
  • Disable – reatime priority threads
  • Disable – Use video as timebase
  • Enable – Extra audio buffering

Then press Down on your remote until you hit the Next button. Click OK until you cycle through all of the remaining screens, but do not hit the back key on your remote as this will exit without saving your changes.


General Playback Alternate Setting with libmpeg2

For Plasma and LCD display running at higher resolutions such as 720p and 1080i there are currently some performance issues with XvMC. For these devices we recomment the selection of libmpeg2 for the MPEG2 decoder. Follow the instructions above but select

  • Preferred MPEG2 Decoder – libmpeg2

Deinterlaced Playback

We highly recommend using a deinterlacer for all playback. Even on an older interlaced CRT display there is a considerable improvement in picture quality by using a deinterlacer.

Should you wish to disable the deinterlacer, for example your have connected a standard TV, you can simply follow the same instructions above but simply uncheck the Deinterlace playback field.
