Something odd in Groove 2.4

I downloaded a pack ripped from the PS2 disc, so it had the BG videos already. But the video accelerates in every song. Is there a way to fix this?

Also, I tried to modify keymaps.ini for spread, but the keys are not registering:

[dance]

Controller1_Down=,,Key_down
Controller1_Insert Coin=,,Key_F1
Controller1_Left=,Q,Key_left

Controller1_MenuRight=,,Key_pgdn
