Renaming Movies



I have a lot of recorded movies in a movies folder with letter grouping sub folders, as it's easy to see something in the epg or rs and end up with duplicates I go through and rename them all to remove the date time stamp I.e Moulin Rouge!_20140302_2100.ts to Moulin Rouge

I tried tidy and dedup but it wants to rename some movies very oddly, is there any clever method I can use, I've not experimented with sweeper or the likes, I manually move them after recording and rename but with 300gb + I'm being lazy I guess !
