That's my impression of the previous DVD too. I watched it again yesterday, and it's not just a "getting used to it" factor IMO. The beginning minutes of this movie on disc are just plain BAD.
Hoping that one of you achievers here can answer this: who is the band "Big Johnson" that's listed in the final credits as having done the cover of Viva Las Vegas, the one that Bunny is listening to in her car as she drives by, right after The Dude gets kicked out of the cab for hating the fucking Eagles? I like that version, at least what we hear of it in the movie, but I can't find anything on-line about it.
