[mythtv-users] Sandy Bridge Graphics w/MythTV

[jzigpublic]

I came across the following solution for Sandy Bridge Video Tearing in 
MythTV.  The quote was pulled from this site:
https://bugs.freedesktop.org/show_bug.cgi?id=37686
It worked for me with an i3 CPU and an Intel motherboard with Intel 
HD2000 on-board graphics.  No more tearing.  I'm using MythBuntu 11.04.

> Select Utilities/Setup ->  Setup ->  TV Settings ->  Playback
>    Select Next 3 times
>    On Playback Profiles (3/8) page:
>      Select "Add New" by Current Video Playback Profile
>        Enter Playback Group Name:  Intel HD Graphics
>          Select OK
>      Select "Add New Entry"
>        Match Criteria:>=        W: 320        H: 200
>        Match Criteria:           W: 0          H: 0
>        Decoder: Standard         Max CPUs: 2   Y - Deblocking filter
>        Video renderer: xshm      OSD renderer: softblend   Y - OSD fade
>      Select Next
>        Primary deinterlacer:  linear blend
>        Fallback deinterlacer: linear blend
>        Custom filters:
>      Select Finish
>      Select Next 5 times
>      Select Finish
> Select Playback (again)
>    On Playback Profiles (3/8) page: (now shows Intel HD Graphics)
>      Select "Add New Entry"
>        Match Criteria:>          W: 0          H: 0
>        Match Criteria:           W: 0          H: 0
>        Decoder: Standard         Max CPUs: 1   Y - Deblocking filter
>        Video renderer: xv-blit   OSD renderer: softblend   Y - OSD fade
>      Select Next
>        Primary deinterlacer:  Yadif (2x)
>        Fallback deinterlacer: Yadif
>        Custom filters:
>      Select Finish
