Lip sync in Lunar Silver Star

I started playing Lunar: The Silver Star (ISO+MP3 noname release) and I found that certain scenes have perfect video/audio synchronization, while others are off by a second or two. Does this disturb anyone else other than me? =)

I dislike seeing all these rips without NFO's or anything regarding the methods used for the release. I really dislike the 128 kbps MP3's =( I guess beggars can't be choosers though eh?
Did you get your copy from elportal? I have the same trouble with mine. Well, that and the fact that mine's just a shitty rip as far as I can tell.
