Missing 10m scenes on part2 of pilot PAL dvds

Hi all, i just noticed my seaQuest Season 1 dvds are missing 10 minutes or so on the second part of the pilot episode (right before and after the starting credits). I own the 6 singlesided discs (region 2 PAL spanish/portuguese) set release, containing english and spanish audio and spanish, portuguese and english subtitles. The discs are labeled 45916.x/U3/R0 (where x is a number ranging from 1 to 6).
At least the part 2 of the pilot episode has been edited in some way (it runs at about 33m instead of 44m) but i'm not sure about the rest of the episodes. Does anyone else experienced this problem on any other release, especially zone 1? If so, please let me know, as i would love to trade my set for a proper, uncut one.
Thanks a lot!
