Hello, I am sorry if this have been discussed before, but I did not see anything about this in my search. I have a car that is able to play DVD-A discs, and I have noticed that they sound better (in my opinion) than my ipod playback through USB/Bluetooth streaming. A couple of questions: 1) I know you cannot rip a DVD-A or SACD to your PC, but if a record company wanted to put out an album with the same type of 5.1 surround mix as they would have with a DVD-A, could they do that through a lossless formart like FLAC, etc.? 2) If they did produce a file like that, and say they made that file available via itunes or HD tracks, could an ipod/media player be able to play that file through a USB connection or bluetooth streaming? I know that FLAC cannot be played on an ipod, but there are other formats that do. Would there have to a new ipod to be able to play this type of music? Also, would I have to upgrade my system to play it back in my car? Sorry for the what if question, but I was just seeing if the technology is already out there. I also understand that it would take a lot for this to be available mainstream, but I thought I would ask. Thanksfor humoring me!
