Hello, New to this site, so forgive me if I placed this question in an incorrect catagory. I purchased a DYNE Digital Recorder, Model DR1512 a while back. There was no users guide with the purchase. I've been struggling to figure out the basic operations of this unit, with this being my biggest problem. I record files in both the .TVF and .TVC extensions. On playback using the recorder, only the first 10 seconds of each file will play, then it stops. The display function shows the full time of each file, but, only the first few seconds play. I'm hoping that this issue is something simple I overlooked, possible setting out of wack? If anyone has had a similar experience with this recorder, advice would be much appreciated. Thank you. Gerry
