I think it was a hardware issue after all. Without changing anything in my setup, it hasn't happened anymore for 3 months now. All I did was to be careful about the temperature of the computer, e.g. not turning it on too long before recording time. I think the machine has air flow issues and overheats, and this must be what caused the sound recording to break in the PVR. -- David Faure, [EMAIL PROTECTED], sponsored by Trolltech to work on KDE, Konqueror (http://www.konqueror.org), and KOffice (http://www.koffice.org). _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
