My Sony PDWF350L camera has been giving me a warning "ILL.REC!" after the camera has been on for an extended amount of time. When this comes on the camera quits recording until I turn the camera off and then back on. It will run for a while and then happen again. The Sony manual says that the VDR should continue to record. However it appears this is not the case for me. Has anyone else experienced this? Any ideas? I have done a complete factory reset and updated all firmware to no avail. Thanks for your response in advance.
