Delayed sound on dvd

Hi...Let me get to the point..I burned the movie aviator using nero express 3 but my sound is delayed by about 15 seconds.

Let me give u teh facts and info:
I have a DVP642/37 dvd player by philips. Thsi dvd player plays Divx and Xvid. So far I have had no problem with the burn. I burned the dvd as a data dvd. I burned 300 and apocalypto like that and it worked. But then I burned teh aviator teh same way and when I listened to it on dvd teh soudn was like 15 seconds behind. On computer it works fien tho.

Also teh movie aviator is devided into two parts. The fisrt part has delayed sound but the secodn one doesn't. They both have the same video and audio codecs (found out using video inspector).

First half
Video BitRate: 1213kBPSAudio sample rate: 48000Hz
Audio BitRate:123 Kbps
for video: Xvid MPEG-4 codec, audio: MPEG 1 or 2 Audio Layer3 (MP3)

Secodn half
Video BitRate: 843 KbpsAudio sample rate: 48000Hz
Audio BitRate:139 Kbps
for video: Xvid MPEG-4 codec, audio: MPEG 1 or 2 Audio Layer3 (MP3)

Could teh fact that the video bitrates on the two movies are so different be teh problem? I dunno, mayeb you know
...tahst why Id like to ask all u pros out there to help me out.
Any help or suggestions are much appreciated
