[mythtv] external deinterlacers/filters for MythTV?

[Jeroen Brosens]

Is there any possibility to have external deinterlacers or filters 
active in MythTV besides the ones that get installed? As far as 
deinterlacing is concerned I experience judder (non smooth image) and/or 
jitter (vertical jumping image) when using bobdeint. I already posted 
about this last week, with not much response. How about the DScaler 
software (GPL) that is available for Windows?

The thing is, that the SiS X driver (ASUS Pundit, many users!) doesn't 
support OpenGL, thus no Vsync calibration, and so deinterlace timing is 
off when it is out of sync with vertical refresh. It leads to field 
reversal -> jitter. On top of that, the TV-out (CRT2) of the SiS video 
bridge can only output progressive material, so it needs either a 
software interlacer (bobdeint, see above, the only one that maintains 
full frame rate) or a VGA to RGB converter cable which I am soldering 
right now. Since it is not expected to work on all systems I am still 
open to any suggestions about good deinterlacing.
