Try putting your conditions as part of the join:
SELECT * FROM shop.dvds
LEFT JOIN
oldtables.movies
ON
mov_id = dvd_mov_id
AND (
lower(mov_name) LIKE '%superman re%'
OR lower(dvd_name) like '%superman re%'
OR lower(dvd_edition) LIKE '%superman re%'
)
LEFT JOIN shop.data_soundmedia ON sm_info_ean = dvd_ean
I'd also be tempted to look at a tsearch2 setup for the word searches.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
