Getting the cut-scenes?

[Mirinee]

I was annoyed too at missing lots of cutscenes. I missed all the side quest arcs on my first run-through because I did the quests in the wrong order. It's hard to know which character to use/cutscenes to get without using a guide. Flaw in the game.
PSOWorld has guides on the sidequest arcs.

As for which characters to use, I had a list I copied from some guide a while ago. Only the three main characters have cutscenes for the Great Ambition (Pollux) quest.

Hunters:

Fossil Find 2--Sil'fer
Called Out--Sil'fer
Truth Seeker 4--Sil'fer

Tower Check--Kranz
Delicious Dish--Kranz
Poachers--Kranz

Phantom Shop 3--Kylria
Monument Watch--Ino'lis or Kylria
Clean Up Job--Ino'lis
Fish Rescue--Ino'lis

Great Ambition--Sil'fer, Kranz, Ino'lis

Arkz:

Ruin Smugglers--Break
The One I Miss--Break
Lazy Bum 4--Break

Last Chance 1--Lura
Last Chance 2--Lura
Last Chance 3--Lura
Across Time 3--Lura

Research 1--Endu
Recon Duty 2--Endu
Lazy Bum 2--Endu
Puzzle Solving--Endu

The Final Battle-- Break, Endu, Lura
