need help on my great avs

[X-Mat]

I just made this great (2d) avs. Its so nice as one of my first avs but there's 3 big problems about it.

first, it is very slow, and its the worst avs in pixel doubling mode, so dont even try it in full screen.

second, there is this very annoying line appearing for no reason in the middle left side of the screen. Its caused by the grid size in the last dynamove. I would be very very happy if someone would solve this little (im sure its a little problem for pros) problem. Either tell me how to or send a corrected version.

finally, the avs only look very nice with my own songs, not because they're special songs, its because of the file type.
This can be explained with a little story:
There was a time when i beggan this avs, it was about 1 year ago, and at this time, i didn't have internet yet, so i did not have any good songs. The great solution I found is (you can laugh) to record songs from the... radio. And you know, the radio and hid annoying little sound. It just hapens that this annoying sound is what makes my avs look great, caus its a constant noise and when there's nothing in the song, it makes white and its ugly. So put your heaviest song and hope its still nice. Maybe ull find it great with white always, its ur opinion.

Anyway, give me your comments, it will be appreciated.

oh sorry I should have put this thread in avs presets,I just didn't think of it.
