I meant recording mode. I could transfer from DV cam to PC without any prob (Playback/VCR control via SW and firewire), but later I noticed I can't use the DV cam anymore for recording - neither by itself, no cables connected, nor when connecting it to the PC again (icon in the Windows explorer opens a "screen" for capturing stills).
Anyhow, I sent it to the service center and they called me back on the same day, couldn't find any problem.
Went there to check and indeed, it worked again. I assume taking out the battery for a long time did the trick - the only thing I didn't do / think of at home.
Happy again.
