NO, its a PAL tv that also accept NTSC.

50 frames is Butter Smoooooth on it ( turrican ect........ )
also 60 frames ( NTSC )

all super smooth.

I would double check on what frequency it's delivering. Obviously you can't be having these issues on 3 different machines with the same mouse. I am sure your TV is the one at fault.

I dont know, the CRT TV works great so far ( and i keep that thing so long as it works ).

Same thing on LCD via RGB-SCART.

No, my CRT TV do not "Accepts PAL as well - as you said"
it is a PAL TV . ( it display also PAL60hz & NTSC 60HZ )

All super smooth, dosent matter PAL or NTSC.
TV is fine

OK so keep thinking that the cause is the least possible, craziest option out there, which is that 3 of your machines have issues :P
I also mentioned the mouse, if it's higher res, it could give pproblems, but you don't test it with an old school tank mouse.

Havent noticed any issues like these with my two CD32 units (connected to 1084 monitor, if it matters).
One unit has SX1, the other FMV.

Try launching a game which uses the mouse: do the mouse movements appear jerky there as well? On all three units?

It depends on the game,
If its "Dos-Friendly" and native installed,
then the movemend is a little bit jerky. ( nothing major )

But if its WHDLOAD or NOT DOS friendly, then its super smoooooooth.

Hmm, interesting at least. Maybe a mousepad would help

Hmmmm, this is quite a puzzle! Now I'm wondering if this has anything to do with the CD32's boot screen being interlaced?

This seems to indicate that the jerkiness does not come from the mouse but from the software which is reading its movements.

For some reason, OS-acquired mouse values are jerky while hardware-read ones are fine.

This means that your hardware is fine and that the issue comes from software, which also explains why it happens on all three consoles. If your consoles have nothing wrong then I guess one would expect to see the same issue on anyone's CD32. Do you have a .iso of a program/game/whatever exhibiting the issue that someone else could burn to try on their own console ?

After that, we will need a volunteer to burn it and test it on their CD32.
