I download some videos on the internet, then i convert them to mp4 and sync them to my ipod touch. But how come the quality of these videos are very bad. Everything appears on the screen is not clear. It is completely different to the videos that i watch on Youtube ( an app in ipod touch) High definition, supper clear. Anyone knows any video file format that make the quality better to watch ! Pls let me know. I tried Quicktime, mpg. For these files, i was able to put them into my itunes but i could not sync them. Dont know why? I even tried avi, mov, but i could not even put them into my itunes. The only file format that accepted by itunes was mp4 . But the quality of the videos after syncing them to ipod was very awful. Pls let me know what i can do.
