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;
1212 ysize = 2*tv_mode->nbr_end + 1;
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.
