Hey,
I know that problem. Captured by FCP the uncompressed .mov files cause a white screen in AE. Right at this hour it forced me to remember…
By exporting it using h264 .mov AE accepts. Well I`m no expert at all for all that container and codec stuff, but I´m really happy with h264`s quality results, so I keep on using it before transfering it to AE.
Unfortunatly I don`t have a solution without compression – give it a try if you want to, or wait for a real expert`s answer.

Btw: Reading your other posts was quite amusing. Your language is so simular to german… also if you don`t want to hear that.
