problem 1: I use appendBytes() to add flv tags(abount 60 seconds flv tags) to netstream, when i seek (seek targe is in 60s), i found the video cannot be play
problem 2: I use appendBytesAction(NetStreamAppendBytesAction.RESET_SEEK) and appendBytes() when seeking, however, i found Flash Player can play but empty buffer,
and i have to request new Flv tags.
