Summary: Some MP3's lose first 2 seconds (approx)

Initial Comment:
Some of my mp3's start playing about 2 seconds into the song.  Most mp3's are fine, but I have several in my collection that this happens with.  All other mp3 players I have play the files correctly.

I narrowed it down to xine-lib-1.1.0 being the last working version of xine-lib.  Versions 1.1.1 through 1.1.7 all exhibit the bug.

I narrowed it down further to the file "xine-lib/src/demuxers/demux_mpgaudio.c"  In the cvs repository, the bug was introduced in the massive update from rev 1.141 to rev 1.142.

If I save demux_mpgaudio.c from rev 1.141 into my sources for xine-lib 1.1.1 or 1.1.7 and 'make && make install', I then have a xine-lib that doesn't exhibit this bug.  I am currently running xine-lib 1.1.7 (un-?)patched in this way.

Obviously this isn't the ideal solution, as all of the updates to the file in the past 2 years are lost to me.  Furthermore, I can't be the only one experiencing this problem, so there's a bug in there and it should be found and fixed.  I've spent way too many hours trying to track down the bug in demux_mpgaudio.c, but the changes are big and way over my head, so I'm stuck.

I'm running Gentoo Linux in 64-bit mode on a dual-core Athlon 64.  Everything's up to date.

I'd be happy to email one of the mp3's that exhibit this problem to any developer that wants to help me solve this problem, but they're all copyrighted by record companies, so obviously I can't upload one here.

I'm happy to help in whatever way I can, but I'm at a loss for figuring it out myself at this point.
