Blurred pixel fonts when in a movie clip

i have a block of text in FFF Harmony, about 200 pixels wide…

when i place it at an exact co-ordinate on the main timeline, it looks great, all pixel sharp as it should be.

but when i put it inside a movie clip which is on the main timeline, still on exact co-ordinates, only the first few characters on each line are sharp, and it gets progressively more blurred the further to the right the text gets.

have tried changing the block of text to dynamic text so the characters are all force embedded, as suggestioned somewhere, but this doesnt help.

any ideas why this happens???
