Ok, Let me first say I don't have the DVD yet, but when I went to Amazon to see if it was released yet, I read a review. According to the reviewer, the audio is in MONO, and it's STILL missing sound effects like Season 3 was. I thought the effects in season 3 might not be that jarring. And t hey arn't when it's something simple like a door slam not being heard. But when Kitt is absolutley silent as he powers up, that IS annoying to watch.. Any word yet on fixes? And I really hope they allow us an option to get thme faster, rather than wait 2 months. I STILL havn't gotten my Thundercat envelope from Warner Brothers.. Thanks!
