well, it's not strange, I had erased records wich worked.
All files in previous screen doesn't work (all recorded until end of program).
one was recorded on the tv screen.
the second was recorded by tvguide
the third was recorded with come back in my music and, read a mp3 file during record.
Now, the same folder with a record working (ie when start/stop manually) and going in my music too.
Then, I can see too there is a tempSBE folder in card1 folder wich is empty.
