Hi.
So far I have extended the VideoElement to support a extended NetStreamLoadTrait as you suggested.
My code is the following:
override protected function processLoadStateChange(
newState:String, newContext:ILoadedContext):void
            if (newState == LoadState.READY)
                 var context:NetLoadedContext = newContext as NetLoadedContext;
                netStream = context.stream;
                if (    !isStreamingResource
                     && (  netStream.bytesTotal <= 0
                          || netStream.bytesTotal == uint.MAX_VALUE
                    netStream.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
            else if (newState == LoadState.UNINITIALIZED)
                netStream = null;
        private function onNetStatus(event:NetStatusEvent):void
            if (netStream.bytesTotal > 0)
                dispatchEvent
                    ( new LoadEvent
                        ( LoadEvent.BYTES_TOTAL_CHANGE
                        , false
                         , false
                        , null
                        , netStream.bytesTotal
                netStream.removeEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
But no matter what I change, always a new Extended VideoElement is created, the playhead backs to 0.
Can you explain more how you would modify the NetStreamLoadTrait or LoadTrait to work together with the seek?
Thanks a lot,
Chaim
