Hi again,
ah ok so isn't really easy to handle that problem to add a fix into RTMPDump.Really pitty.So I have seen another cam site who does also use same command.
Thanks for your new CMD tool version with player output so now its working better.So I made a GUI now (I do code in assembly) which is almost done so just need to make some more little tests to be sure that everything is working well.Below a picture...

...just added some test names but you can add tons of name / tabs etc.
