Problem with command line

[radian]

Hi!
Can’t stop record in pip mode via command line. I start record with command

e:\dvbdream\dvbdream.exe /startpiprec_chno=4

- it works OK. Then I try to stop it with command

e:\dvbdream\dvbdream.exe /stoppiprec_chno=4

- and… nothing happens. The only way to stop recording –

e:\dvbdream\dvbdream.exe /stoprecordall
(or using PIP button > stop all). The log is as follow:

- and nothing more.
Tried to use commands with channel ID instead of channel number – with the same result (using the channel name I get an error). Uninstalled and reinstalled DVBdream – no difference. OS: WIN XP SP2; DVBdream version v1.3c
Any ideas? What a miracle? Help, please, I need it very much.
Thanks
