I recently purchased a Hitachi 57S715 projection tv. It is great but on the HD channels I see a lot of lip sync issues. Anyone else having any issues with this? Hitachi tells me that there is some delay inherient in processing HD signals and there is nothing they can do. Why then can I buy an AV receiver that has a feature to correct for this? But yet the engineers at Hitachi can't put the same circuit in the damn tv??? Anyone have any comments/advice.
