What's the difference?

Hello. Flash Freaks!

now this is the problem:

when i put a button on a layer in the first frame, and i give the button the actionscript:

on (release) {
loadMovieNum(“PHOTOS/PERRY_1.swf”, 1);
}

then file is correctly loaded with good jpeg quality.

BUT!

when i put a button on a layer in the second (or third etc.) frame
and give it the same script, the quality of the jpeg in the swf file is awefull!

Please help!

Why is there a difference in photo quality if you publish fla 1 and fla 2? Very strange…
