Adobe premiere problem

[another_asswipe]

Not sure if I should write this here so sorry if I posted in the wrong section
SO here is my problem: When I tryed to reverse a clip in premiere i switch the speed to -100% and then I get a black screen at then end of the clip ( on the monitor) with a red X on the middle. I tryed to trim the clip but it won't work the black screen is still there. I looking for information on the internet but couldn't find anything
So is there a way to make a reverse clip without having this black thing at the end of my clip ?

You can't overlay it with a different video frame?

so it's like...
Foward video: 1 2 3 4 5 6 7
Reversed: 7 6 5 4 3 2 1 black
and you can't trim the black? this is for clarification

if I overlay it the black part will just move , it will always be at the end of my clip ( same thing happen when I trim it)
"so it's like...
Foward video: 1 2 3 4 5 6 7
Reversed: 7 6 5 4 3 2 1 black"

yes
[edit] I tried several video from anywhere ( not only from my cam) and it's still doing the same thing. Also tryed to reverse the clip from the source ( in the bin) but I still got this weird black screen with a red X
