hi istvan!
a first suggestion: fli-circus. handling all the different aspects of the image conversion must be comparable to drilling fleas 
after a long time of just reading the thread i played for quite a while with this tool and i have to say i like it very much. the thing i like most is the preview-option (PAL-preview! how cool is that!), the real-interlace-mode and the support for all relevant formats.
i don't want to bomb you with feature-requests, but i like to make some suggestions for further improvements. there are only few things i would love to see and these are just ideas, so please don't kill me:
1. your "preview" mode already shows the final result. from my experience and due to the highly saturated nature of the +4-palette i always felt the need to see a preview after all the preprocessing-steps (like gamma-correction etc..). in my converter (see below) i solved this with a preview that shows an "idealised" picture, color-reduced and dithered to the +4-palette.
2. different x-shifts per line (i know, i'm quite fixated on this )
3. interlaced modes where both fields share the same videomatrix. (this should be quite useful for all cases/demos where you don't have too much ram left)
4. a bit more exotic: special support for monochromatic modes. the display-kernel-routine only refetches the luminance-attributes.
5. even more exotic: an adaptive approach that decides if the display-kernel-routine refetches the color or luminance portion to reduce error.

my converter:
you can download a WOP-version of my converter here:

the application is full of rough and dirty code, tends to crash and has lots of inferior approaches (e.g.: i use RGB instead of YUV all the time). so don't look too close
look at the readme-file to see how you can play around with the scrollbars and keys 1-5 to have a quick (pre-)preview. maybe this is something you would like to have in your app aswell. i still think its handy to compare "optimal" versus "possible". that would be even more interesting in your app, since you are able to show a PAL-preview.
