Hi. I have a ATV2 and a Beovision 6 (DVI only). Connected with HDMI to DVI, and from optics to R/L (Converter) My ATV2 i running software version 4.3. No problem. When I upgrade to 4.4 there is no picture on my BV6? Connecting PC monitor to ATV2 - Works. Connecting PC to BV6 - Works. So i ended up downgrading ATV2 to version 4.3. Everything works again
