Every time I download episodes i got an error downloading codec. Can someone help me? I really like Kenan & Kel!!

idk what format they are but you probably need the Xvid codec

http://www.koepi.org/XviD-1.1.0-30122005.exe

see if that works

well when I'm playing the video it stops early only showing a little portion of the full video help plz

I suggest VLC Media Player, it plays various formats/codecs.
