Page 1 of frequency? disk or faulty

when i watched frequency, the talking seems to be very very low to the point i have to strain my ears to hear them and the music very high and yes i do have the volume up very high but cant at night cos neighbours bang on my door, so i was just wondering if it was the disk that is faulty or is that how it was made and if it was made like that it`s s***.

hope someone out there can help me.

p.s i dont have that problem with all my other dvd`s

rented it couple of weeks ago, no problem.
I`d say your disk is faulty

thanks pegasus for helping me out, its going back to the shop tomorrow
