Is it really impossible to do a seamless loop with ext flv?

Hi guys,

I am searching everywhere for a solution for this: I´ve got a seamless video loop as a FLV file. If a play it as an external flv file inside a flash movie, it won´t do a seamless loop… It will do a small but annoying hiccup just at the end.

Is there a way to make it loop seamlessly?

Thanks in advance!
