Query: Player Randomly Turns Off While Watching HD-DVDs

While this unit plays standard DVDs perfectly, it turns off randomly while watching HD-DVDs. I have tested a variety of HD-DVDs. I have even upgraded the firmware to version 2.5 and the problem actually got worse! It's doesn't seem to be temperature related since it can turn off right away, or after watching for 15 minutes. I'm sending this unit back.
