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.
