apple movie trailer problem

after using quick freedom to JB my IPT 2.1.1, i cant view ANY videos on apple movie trailers. it says the following(in red): click download to the file to your/var/mobile/Library/Downloads folder. Warning: if this file already exists in the downloads folder, it will be overwritten so i DL it and touch the "Play in Media Player" button. i get a "this movie format is not supported" message. cant play in dtunes either. is there a add-on or plug-in that i need to DL. PLZ reply here or send me a PM. THX from a IPT Noob

still cant...

that would indicate that something has been installed to pickup downloads, you would need to install mplayer and point it to look at that folder before you could view the file(s). You might also require safari download plugin if it is not installed already.
