Looking at the code, I'm not sure this fix is enough.

Later code has
1209         if (tv_mode->progressive)
1210             ysize = tv_mode->nbr_end + 1;
1211         else
1212             ysize = 2*tv_mode->nbr_end + 1;

So using
286 would result in a ysize = 573
288 would result in a ysize = 577

ie neither are right (576).  Hopefully someone with doco can comment.
