Well, I did it again
I took the USB Flash out from the Dreambox 7000S, inserted it into the PC in order to copy a large recorded file in *.ts format. Just copy, no deletion or anything else.
But when I inserted the USB flash again into the receiver, I had the same weird problem as shown in post #1.
So it looks like the PC is causing some sort of a corruption to USB.
Looks like I have to reflash again tonight.
