I dont think you have to go to italy for those titles! and most of the time the italian dvd´s are only in italian without subs.
why dont you use your honeymoon to have the most beautifull time of your life with your wife, instad of searching for dvd´s
but.... there are good italian dvd´s of massacre time, little rita of the west and west and soda with english audio option.
Probalbly there are more but these three came up.
go for the segio sollima box with run man run, big gun down, face to face - it has italian audio with english subs! great box!!
Italian vhs tapes you are not going to find, they are big collecters items and on ebay they ask around 40 euro for an italian tape!
enjoy your time in italy and say hello to the pope from me
