Background: I was at Best Buy yesterday picking up some DVD's with the wife, and she went to the music section to pick up the SAY YOU WILL Fleetwood Mac CD, so I suggested to pick up the DVD-A for $1 more and I told her that it was in 5.1 and it was recorded in HI-REZ. Then she asked if it would play in the car ?...I said NO, then she said "I don't want it then !!" ... Which brought me to this question : How many sales do you think DVD-A has loss due to the format not being portable ?
