Rotated .png's going jaggy

Here is a wierd one,

I have created some animation with png’s to retain transparancy but when i add extra frames or scenes they turn jaggy.

fine version (1 frame) here
jaggy version (2 frames with a stop) here

any clues?

Just had the exact same problem, occurs with rotated PNG’s and JPEG’s when extra frames are added (included a long explination here: http://www.kirupaforum.com/forums/showthread.php?t=70364)

Have any luck with the problem?
