Just got our Studio convertor with analog audio out. Our first job was SD 720 X 576 the audio had intermittent crackling and was unusable with all 4 channels. The unit is not detected with the convertor utility but our other BMD convertors are. We had this audio problems a couple of years ago with the sdi to audio convertor but it was fixed with a firmware update it seems a similar issue. We use Sony PDW700 cameras. The sdi video output worked fine. I am yet to test in HD but am very nervous. Any help appreciated
