quick time 'this is not a movie file' error message
PLEASE HELP!
i've recently downloaded some movies off the internet (.avi files) and although all have originally opened and played in quicktime, i am now getting 'this is not a movie file' error messages for all of them. I've had this before and restarting the computer has usually helped - but not this time. I've also tried reinstalling quicktime, as well as installing divx (i get an error message saying this file cannot be opened). for some reason i can't install VLC (some message about not being able to mount).
I've also burnt the files to a cd and tried playing from there (Rather than my external hard drive) but still won't work. The files won't even open up a preview... i really don't understand what could have happened though - i've opened and played all of them when i first downloaded them and they worked just fine!
i'd appreciate any help.
cheers
