Help Please. 1198 newbie but been studying this forum and other info a lot. Thanks for the forum, great info. First attempt to view SI recording on PC, not working. Firmware on 1198 is the most recent, updated a few weeks ago. Recordings won't play on Humviewer but Humviewer will play the test file downloaded from their website. I assume compatibility issues between new firmware and latest ed. Humviewer. Tried viewing on XP and Windows 8 PCs. Recordings were stopped properly. One recording is a test run of about 7 minutes from simulation mode. All recordings seem to have all the correct folder, *.dat file. *.son and *.idx files. They will playback on the 1198 unit. Any ideas or recommendations or another viewer known to be capable of viewing the SI recordings from latest firmware on 1198? Thanks very much for any help. Thanks again for such a great forum.
