Those do look better than the jpegs, actually. It might give a better result if you sample down to 8-bit (without dithering) and GIF them rather than using jpeg. I might try this at some stage. The images seem quite dark, btw. This may be a function of display gamma, since I've speculated before that your display is gamma corrected while most other kinds of display (except SGIs) are not. > The images always DO > have more than 16 colours, because there is an antialiasing between pixels; > remember Sam's pixels are actually rectangular instead of square, so there > can _never_ be an exact 1:1 mapping without distorting the shape of the > picture. Does the TV card give a good enough resolution to be able to squash it and get an exact 1:1 mapping?

If it does this in a predictable way then it might be possible to reverse the effect. On the other hand, from a brief look at some pictures it doesn't seem to have been done in any kind of logical manner. (Why haven't you sent it back?) imc
