[mythtv-users] HTDV 1080i source at 1080i DVI - Interlace field order backwards on GeForce 6200

[Paul Robertson]

This talking to myself is quiet therapeutic. :-)

 

Spent more time fretting over this issue, and decided to put the FX440 back
in the system and take another close look.  With the FX440, I discovered the
following two cases appear virtually the same when displaying 1080i source
on 1080i DVI.

 

Nvidia 8762 driver + XvMC + OpenGL Vert Sync + No De-interlacing

 

Nvidia 8762 driver + XvMC + OpenGL Vert Sync + Bob De-interlace

 

Both of these FX440 cases look just like what I see with the GeForce 6200
using Bob de-interlace.  It appears with the FX440 that "no de-interlacing"
is actually being bob de-interlaced.  I think this is why I had never
observed the field order issue previous to installing the Geforce 6200.

 

Well why not just turn on bob de-interlacing for the 6200 and be done with
it?  Well, the 1080i image quality produced with the 6200 using "no
de-interlacing" is much better, (.that is as long as the field order stays
correct).
