All valid points from you Steve, Dragonballs problem seems to be timing related since it works when he's using a slower clock than 4Mhz. But at 4Mhz it seems to skip the first characters, if I understood it correctly.

I think the 500 idea was good enough since 500-256=244. Should be more than enough for a data delay...
Put a 5 second pause at the beginning of the program, that'll extinguish any doubt about the power up on the LCD. If that don't fix it, it's something else.
