Query: HDCD incompatibility

This DVD player has trouble playing HDCDs. I returned the unit back to the store where i purchased it and got a replacement unit, but still the second unit suffers the same problem. I was told by Toshiba to bring the unit to one of the authorized warranty service center to have the BIOS upgraded. i haven't done so, but those who are thinking about purchasing this particular model 2700, consider yourself be warned.
