"cannot play on this ipod"

I can download a movie with no problems. The quality is great. I can move it to iTunes fine. BUT when I try to move it on to my iPod and/or iTouch I get the message "This movie can not play on this iPod/iTouch". Is there anyway to correct that so I can move them on to the device. I have some great movies I would like to travel with me.

Thanks

iTunes is less fussy than iPod when it comes to videos. iPod is quite specific. It accepts only two types of video, MPeg 4 & H264 which is an advanced type of MPeg 4 video. The limitations are in video dimensions & in audio specifics.
You will find more information here: How to transfer to my iPod (& iTunes) - for video. Half-way down that post you will see the specifications for video for iPod.

You may need to convert the video so it's iPod compatible in viewing dimensions & audio specifics. Video extensions would be mp4, mov, m4v ... as far as I know. There are some converters mentioned there. Do not use Anapod. I really need to update that page again. So many links die so quickly.
