Where can I download some high dvd quality ff9 video?

nowhere. ff9 was released on cd for psx, not ps2. the video is at standard definition. any video with a higher resolution has simply been stretched.

But there's the ff8 videos that were of dvd quality.

they may have been released on DVD but that doesn't mean they're DVD quality. the best quality available is what's already on the discs, which you can rip with psmplay etc.

oh i see, thank you :)

You CAN find cutscenes from all Final Fantasy games that have them and they have very good quality. Check here:

Blue Laguna - http://bluelaguna.net/movies/ff9/fmvs.php

File Front - http://www.filefront.com/ (search for Final Fantasy)

Blue Laguna is so much better, but I've had some problems with it's videos in the past.
