I'll just repost my list of games that I tested and their results from github over here for more exposure:-
(tested with 0.7.6-1025 which was the first build to have video support)
FFVII CC:- Yes, the intro FMV plays now. The FMV audio itself is rather choppy though
Monster Hunter Freedom Unite US:- Just a black screen shown for the FMV, Background FMV audio can be heard nicely
Soul Calibur:- This one is just perfect. FMV and FMV audio plays and ends smoothly. The main title screen is also an FMV so it now displays properly.
Gods Eater Burst:- Just a black screen shown for the FMV. Background FMV audio plays nicely though.
Persona 3 Portable:- This one is also perfect. FMV and audio plays nicely now.
Gladiator Begins:- relies on psmf video. Doesn't play properly.
Tekken 5 DR:- This one is quite severe. It crashes the emulator completely when attempting to load the intro FMV. Temp solution for now is to quickly skip intro FMV playback by hammering the start button, otherwise, it WILL crash the emulator. Logfile:-

Tekken 6:- Funnily enough, Tekken 6 plays the intro FMV perfectly with the correct audio and all. Even transitions to the main menu properly. (No more "GET READY FOR THE NEXT BATTLE!!" spam)
Gundam v Gundam Next Plus:- Intro FMVs play properly with smooth audio playback too.
Trails in The Sky:- The short FMVs in the beginning play properly.
FF1:-- FMV can be observed, video playback is rather choppy, but the background audio is working smoothly,
FF2:- The emulator just hangs when it comes to the intro FMV. Just a black screen.
FF3:- This one is perfect, both FMV video and audio playback is smooth.
FF4:- FMV can be observed, but the video and audio are playing back in fast forward. It's like I held down the turbo button for the video.
FF Type 0:- Choppy audio playback in the FMV. FMV can be seen perfectly.
All in all a mixed bag, improvements can definitely be done.
