I bought the back to the future trilogy for $22.00 just last week and allthough most of the 3 DVDs are xlnt quality I have found on the 2nd dvd BTTF 2 in a couple of spots the sound warbles when music is played, thinking this was a bad dvd I took it back and traded it for another set and on the 2nd set it does the same thing, so my question is, does anyone have the same problem with their BTTF 2 dvd or any of the BTTF trilogy?

I think they're all like that. I remember when the trilogy first came out people were complaining about having problems with the DVDs

I don't recall noticing anything like that when I bought the trilogy a couple years ago. Of course I'm not very observant, so it could have been there, and I just didn't notice. I'll have to check that out again sometime, and pay closer attention. The only problem I had with the DVD's, was that the color wasn't very good in certain scenes. Especially in part two. There was a weird glare coming off Marty's red jacket throughout most of the film. Other than that, I didn't notice many problems.

I haven't noticed any problems with the DVDs since I bought them a year ago. Then again, my DVDs are Region 2; I'm assuming yours are Region 1, so there may be some small problems that are confined to the Region 1 DVDs?
