iPod touch Podcast video did not play?

Hi

i downloaded some podcast, with a note "enhanced video", but after syn in itune, i open the podcast section in my ipod touch, i didnt see any video, only sound coming though.

is it normal. As i noticed, the file size is like 140mb, and when i open them thru my itune, i can watch the video perfectly fine.

let me know,

oh simple enough that i didnt even know.

thank you for pointing out.
