Hello,

I plugged my C64 to my PCs TV-card and currently use DScaler with Old
Game filter.
This seems ok, but its not optimal yet.

The problem with a TV card is, that for usual the application collects
two half frames, the one with the even and the one with the odd lines and
combines them - giving a 25 Hz playback.
So that means for C64 it mixes two frames to one.

In my opinion best would be to get a half frame, double the line
height and display it at 50 Hz.
The odd line frame should not be moved down one pal line, cause this
gives a 25 Hz 'hopping' of the frames.

Another point is, that it would be fine to sync the 50 Hz to the
PC-monitor.
This means I can set my monitor to PAL resolution at 50 Hz, though
it's this way not really synced to the C64s signal.

Ciao...
...Micha
