I guess I'll just post excerpts from my custom rename file, with explanations; I believe many can be incorporated into the main scraper / rename DB:
<rename id="tt1622547" title="30 Minutes or Less" />
More of an IMDb error (?); they list main title as "30:Minutes of Less" - I can't seem to find any references for this spelling of the title
<rename id="tt0078243" title="The 36th Chamber I: ...of Shaolin (Shao Lin san shi liu fang)" sortby="36th chamber of shaolin 1978" />
<rename id="tt0081494" title="The 36th Chamber II: Return to ... (Shao Lin da peng da shi)" sortby="36th chamber of shaolin 1980" />
<rename id="tt0089029" title="The 36th Chamber III: Disciples of ... (Pi li shi jie)" sortby="36th chamber of shaolin 1985" />
Grouping, may wait until there are improvements in foreign title grouping
<rename id="tt0091431" title="Armour of God I (Long xiong hu di)" sortby="Armour of God 1" />
<rename id="tt0099558" title="Armour of God II: Operation Condor (Fei ying gai wak)" sortby="Armour of God 2" />
Grouping, may wait until there are improvements in foreign title grouping
<rename id="tt0095800" title="The Bear (L'ours)" />
Somehow, IMDb+ doesn't pick up English name, and lists it simply as "L'ours"
<rename id="tt0092263" title="A Better Tomorrow I (Ying hung boon sik)" sortby="Better Tomorrow 1" />
<rename id="tt0094357" title="A Better Tomorrow II (Ying hung boon sik II)" sortby="Better Tomorrow 2" />
<rename id="tt0098691" title="A Better Tomorrow III (Ying hung boon sik III jik yeung ji gor)" sortby="Better Tomorrow 3" />
Grouping (mainly for sorting), may wait until there are improvements in foreign title grouping
<rename id="tt0093978" sortby="chinese ghost story 1" />
<rename id="tt0100625" sortby="chinese ghost story 2" />
<rename id="tt0102932" sortby="chinese ghost story 3" />
Default sorting doesn't work
<rename id="tt0109445" title="Clerks" />
More of an IMDb error (?); they list main title as "Clerks." - I can't seem to find any references for this spelling of the title
<rename id="tt0082198" title="Conan the Barbarian" />
<rename id="tt0816462" title="Conan the Barbarian (Remake)" />
This one is more of the personal choice, don't think there is a consistent usage of Original vs. Remake. In this case, I believe most people will mean 1982 when mentioning the Barbarian without clarification.
<rename id="tt0103873" title="Dead Alive (Braindead)" />
Another optional one - the main IMDb title is Braindead, but the main poster right next to it says Dead Alive.
<rename id="tt0073582" title="Deep Red (Profondo Rosso)" sortby="deep red profondo rosso" />
IMDb+ picks up "The Hatchet Murders" instead of the more common "Deep Red" as an English name
<rename id="tt0205000" title="Deuce Bigalow I: Male Gigolo" />
<rename id="tt0367652" title="Deuce Bigalow II: European Gigolo" />

<rename id="tt0419954" title="McDull II: Prince de la Bun" />
<rename id="tt1430622" title="McDull IV: Kung Fu Kindergarten" />
Grouping
<rename id="tt0057591" title="Monsieur Gangster (Les tontons flingueurs)" />
Picks "Les tontons flingueurs" as both English and foreign name; guess this might be also an IMDb issue
<rename id="tt0335345" title="The Passion of the Christ" />
IMDb+ picks up "The Passion Recut" as a title??
<rename id="tt0093304" sortby="prison on fire 1" />

<rename id="tt1401143" title="Rare Exports: A Christmas Tale" />
IMDb lists "Rare Exports" as foreign title, so by default imported title becomes "Rare Exports: A Christmas Tale (Rare Exports)"
<rename id="tt0105287" title="Sex and Zen I (Yu pu tuan zhi: Tou qing bao jian)" sortby="sex zen 1" />
<rename id="tt1365048" title="Sex and Zen 3D: Extreme Ecstasy (3D rou pu tuan zhi ji le bao jian)" sortby="sex zen d3 1" />

<rename id="tt0080923" title="The Three Mothers II: Inferno" />
<rename id="tt0804507" title="The Three Mothers III: Mother of Tears (La terza madre)" />
This one exists in the main rename DB, but instead of "Dario Argento's", the trilogy is called "The Three Mothers"
<rename id="tt0487176" title="Tom and Jerry: The Fast and the Furry" sortby="tom jerry 2005" />
<rename id="tt1722638" title="Tom and Jerry: Meet Sherlock Holmes" sortby="tom jerry 2010" />
There is a crapload of T&J movies/series, so didn't number them; for sorting mostly
<rename id="tt0310775" title="The Vengeance I: Sympathy for Mr. Vengeance (Boksuneun naui geot)" />
<rename id="tt0364569" title="The Vengeance II: Oldboy (Oldeuboi)" />
<rename id="tt0451094" title="The Vengeance III: Sympathy for Lady Vengeance (Chinjeolhan geumjassi)" />
Grouping, may wait until there are improvements in foreign title grouping
<rename id="tt1117667" title="XIII: The Conspiracy" />
By default pulled in as "XIII"
<rename id="tt0363226" title="Zatoichi (Zatôichi)" />
By default, English title is pulled in as "The Blind Swordsman: Zatoichi"; this is not the main IMDb title, and not commonly known as such, and screws up sort order (B vs Z)
Hope this helps.
