I have this problem too. ( with cs4 )
sometimes i change properties in “memory & multiprocessing” it will be correct. maybe i was casual!. but i do not know what i do when occuring this error.
my format is mpeg2.
another question: in your opinion will i have this problem with format of camera sony EX1?
i will work with EX1 in HD format (for chromakey), then transform it to sd pal.
my language English is bad. excuse me.
