I just took delivery of the FS-4. I have my dvx set for external recording, and the FX-4 set to "tapeless" recording. When I try to record to the FS-4 by pushing the record button on the dvx, sometimes it works fine, othertimes it records for a few tens of seconds, then stops on its own, and other times the recording to the FS-4 does not start at all. The FS-4 user manual is not extremely helpful, and I am wondering if anyone out there is aware of any listings of settings for both the dvx and FS-4 that might eliminate some of these odd things I am observing??
