"The scan doubler & Flicker Fixer in the PIV is not perfect though. It shows some artifacts when scan doubling high speed interlaced images.
If MASTATABS ever decides to release the source code for it I'd give it a go at fixing it (if technically feasible)."
I think the problem there is that the PicassoIV's normall output is progressive, so when it mixes both fields into one frame you see interlaced artifacts. Since the FliFi feeds the GPU you'd have to program a deinterlacer for it:) Maybe it's possible, at least for a basic deinterlacing algorithm...
Other thing I remember is messing with the frequencies, for example, would it be possible to output a 100Hz interlaced screen instead of a 50Hz progressive one ?
One of these days I'm gonna try it, right now my 4000T with PicassoIV hasn't been turned on for more than an year :-o There's a good explanation though, I only have a 3640 on it...
