I've been offered a G98 for a very reasonable price. According to the seller, the G98 was recently serviced and the optical drive was replaced. Does anyone know whether this means that the G98 will no longer be able to play DVD-Audio discs? I thought I read in a forum post that certain repairs to G series DVD players resulted in a loss of DVD-Audio playback capability.
