Its acually very simple to know if a replay will work or not. Since 1.05 is only compatible with 1.05 replays. Meaning all prev patches will bug. 1.04 on the other hand will work with 1.03-1.04 replays, and since no one watches 1.00-1.02 replays now days, these 2 patches are the only one you need to watch replays. Just look at the date of the replays. If its 2012 and earlier than you can assume its 1.04/1.03.
A tip would be to get switcher if it works for you, or just switch manually between 1.04 and 1.05, since there are no good 1.05 replays tbh.
And no if a rohan mirror ends with peasants only then one of the players most of been rly poor at the game or greatly outplayed.
